First off, the Python code was unnecessary in this case, because it
would be cheaper to use the pygmentize app included.

Second off, CSS is available at
https://github.com/richleland/pygments-css or by running `pygmentize
-f html -O full FILE`.

Gmail automatically hides long quotes.  This is helpful in situations
like this one.  More mail software should implement that
functionality.  Seriously: once you go Gmail, you never go back.

Or something even better: a mailing list.
http://mail.python.org/mailman/listinfo/python-list is where you can
find it.  Much friendlier than Usenet, and the software itself is
developed by the FLUFL.

They shouldn’t care because Usenet users often yell “Get off my
lawn!”.  Young people don’t use newsgroups.  They don’t even know what
Usenet is.

I have been seeing those mails for a long time.  Why didn’t anybody
ban that guy?  If it comes from Usenet (and headers say it does), and
you can’t destroy stuff easily there, maybe just put a ban on the
Mailman side of things, making the world much better for at least some
people?

A filter on this guy altogether would be.  He sent 24 messages there

There is no real reason to do this.  `str.format()` is the new shiny
thing you should be using all the time.  Also, '%' is BINARY_MODULO
(where did you even get that name from?) if and only if you have two
numbers, and it performs the modulo division (eg. 27 % 5 = 2)

This will make your code unportable and useless, depending on one
patch you made.  Please don’t do that.  Instead,

In Python?  Tough luck, every int is signed.  And it isn’t just a
sledgehammer, it’s something worse.  Just do that:

>>> sys.stdout.write('Number = {:,.0f}\n'.format(x))

Much more peaceful.

You can also do a print, like everyone sane would.  Where did you
learn Python from?  “Python Worst Practice for Dummies”?

You would need to convert them to strings first.  You may want bin()
and hex() for that.  And if you want to convert 'q' to 0x71,
hex(ord("q")).  And if you want to turn 'hello' into 0x68656c6c6f, you
would need to iterate over 'hello' and run the above function over
every letter.

Also, you are able to display Unicode characters, too.

In other words: Nikolaos is trying to do something HORRIBLY WRONG

1. Try re-naming the files to real utf-8.  Make sure your terminal
works on UTF-8 characters.
2. Get rid of your bullshit system and use Flask or Pyramid.  It will
make your life much easier.
3. Put the files in a directory on your server and tell Apache to
create an index, making your life easier, but not as easy as it would
if you did (2) and anywhere near as easy as (2) and (3) combined.

If they do, they are already indexed.  Now link stuff to that

It is required so the computer can know where characters begin.
0x0080 (first non-ASCII character) becomes 0xC280 in UTF-8.  Further
details here: http://en.wikipedia.org/wiki/UTF-8#Description

http://en.wikipedia.org/wiki/UTF-16#Code_points_U.2B1_to_U.2B10

Long story short: codepoint - 0x1 (up to 20 bits) → two 10-bit
numbers → 0xD800 + first_half 0xDC00 + second_half.  Rephrasing:

We take MATHEMATICAL BOLD CAPITAL B (U+1D401).  If you have UTF-8: 𝐁

It is over 0x, and we need to use surrogate pairs.  We end up with
0xD401, or 0b11010101.  Both representations are worthless, as
we have a 16-bit number, not a 20-bit one.  We throw in some leading
zeroes and end up with 0b11010101.  Split it in half and
we get 0b110101 and 0b01, which we can now shorten to
0b110101 and 0b1, or translate to hex as 0x0035 and 0x0001.  0xD800 +
0x0035 and 0xDC00 + 0x0035 → 0xD835 0xDC00.  Type it into python and:

>>> b'\xD8\x35\xDC\x01'.decode('utf-16be')
'𝐁'

And before you ask: that “BE” stands for Big-Endian.  Little-Endian
would mean reversing the bytes in a codepoint, which would make it
'\x35\xD8\x01\xDC' (the name is based on the first 256 characters,
which are 0x6500 for 'a' in a little-endian encoding.

Another question you may ask: 0xD800…0xDFFF are reserved in Unicode
for the purposes of UTF-16, so there is no conflicts.

yup.  α is at 0x03B1, or 945 decimal.

Not necessarily, as CJK characters start at U+2E80, which is in the
3-byte range (0x0800 through 0x) — the table is here:

Actually, Nikolaos should be happy I didn’t bother to learn Greek and
pony up €6 to actually call those seventeen numbers, as roaming is
friggin’ expensive, and that’s assuming that a minute would be enough
to tell those people what is going on, and not forgetting that I live
in a country where the minimum wage is less than €400, and that the
number includes taxes and such.

Next time, do a more fair comparison.

I created an empty git and hg repository, and created a file promptly
named “file” with DIGIT ONE (0x31; UTF-8/ASCII–encoded) and commited
it with “c1” as the message, then I turned it into “12” and commited
as “c2” and did this one more time, making the file “123” at commit
named “c3”.

[kwpolska@kwpolska-lin .hg@default]% cat * */* */*/* 2>/dev/null | wc -c
1481
[kwpolska@kwpolska-lin .git@master]% cat * */* */*/* */*/*/* 2>/dev/null | wc -c
16860 ← WRONG!

There is just one problem with this: an empty git repository starts at
15216 bytes, due to some sample hooks.  Let’s remove them and try
again:

[kwpolska@kwpolska-lin .git@master]% rm hooks/*
[kwpolska@kwpolska-lin .git@master]% cat * */* */*/* */*/*/* */*/*/*
2>/dev/null | wc -c
2499

which is a much more sane number.  This includes a config file (in the
ini/configparser format) and such.  According to my maths skils (or
rather zsh’s skills), new commits are responsible for 1644 bytes in
the git repo and 1391 bytes in the hg repo.

(I’m using wc -c to count the bytes in all files there are.  du is
unaccurate with files smaller than 4096 bytes.)

Better: a programmer should know how to convert hexadecimal to decimal.

0x1B = (0x1 * 16^1) + (0xB * 16^0) = (1 * 16) + (11 * 1) = 16 + 11 = 27

It’s that easy, and a programmer should be able to do that in their
brain, at least with small numbers.  Or at least know that:
http://lmgtfy.com/?q=0x1B+in+decimal

Or at least `hex(27)`; or '`{:X}'.format(27)`; or `'%X' % 27`.  (I
despise hex numbers with lowercase letters, but that’s my personal
opinion.)

You didn’t test the code, did you?  Because the code you posted is
right.  Remember to always test code before submitting.  And note that
the getpass module is what you should use for that second thing in
real life, for the security of your users.

That is not necessary.  Because it is a sane OS, it is likely that
hunspell is packaged in the repositories of OP’s system, and might be
even installed there.  And if the package is installed, hunspell
should reside in /usr/lib/libhunspell.so or a similar place.

Then you need to get your hands on a copy of Windows.  Or try messing
with Wine (you would need to install the Python interpreter for
Windows there), but that might not work properly.

And ctypes is used to use functions provided by C libraries on your
system, that is .dll files on Windows and .so files (shared object
files) everywhere else.

The only thing SFTP and FTP have in common is that they are Internet
protocols.  Inside, they are much, much different.  And you should
NEVER use FTP.  (also, why Notepad++?  I’d suggest getting a better
editor first.)

You need to reconfigure FileZilla then.  Site Manager (first icon on
the toolbar) → your site → Charset → Force UTF-8.

Under Windows?  I suggest installing Cygwin or switching over to
Linux, for your sanity.  If you don’t want either, look for a Windows
port of rsync.  The next step is to read the included man page.

CGI?  Is this 2000?  Nobody uses that wording these days.

I’ve yet to see a Windowsy editor with rsync support.  But you should
choose the editor that works the best for you, not the editor which
has rsync support.

I, for one, use sftp or edit directly on the server with vim, my
editor of choice.

This is a capital Eszett.  Which just happens not to exist in German.
Germans do not use this character, it is not available on German

And, surprise surprise, STRASSE is the example the Council for German

Why do you want the paths to the fonts?  You do not need them 99.9% of

Then do a nice little `if` checking the user’s OS.

http://docs.python.org/2/library/sys.html#sys.platform hints what to use,
and you need to do:

if sys.platform.startswith('win') or sys.platform.startswith('cygwin'):
FONTDIRS = [os.path.join(os.environ['WINDIR'], 'Fonts')
elif sys.platform.startswith('darwin'):
# [see below and devise it yourself]
else: # linux, *bsd and everything else
# [see below, commit suicide and develop this bit]

Windows:
The easiest of those three, all the fonts are in %WINDIR%/Fonts.
In Python: os.path.join(os.environ['WINDIR'], 'Fonts')

Mac OS X:
http://support.apple.com/kb/ht2435 (and not all of them are
guaranteed to exist).  `os.expanduser()` may be useful for
that first one.

Linux, and everything else running that fancy open stuff (eg. *BSD):
Hardcore.  You just need to parse a nice tiny 155-line XML file.

It’s /etc/fonts/fonts.conf, and it has some  tags.
Some of them may have a `prefix="xdg"` attribute which makes you
prepend the value with $XDG_DATA_HOME (~/.local/share if that is
empty).  You also need `os.expanduser()`.

Oh: and you need to go recursively through them, as subdirectories
are also checked for fonts (and it probably goes further)

One more thing Devyn should do is watch the “To:” field and make sure
it says python-list@python.org, because the above message was sent to
Chris only, and that is not what should happen most of the time.
Another option is to use Reply All, but it will make old Usenet hags

Apparently, it comes in plaintext.  Mailman does not say that it

You already asked this on Thursday.  And the answer is probably “no”.  Creating

Under X11-based systems, you would have to call the dbus notification
APIs and pray that the user has something to handle it running (KDE,
GNOME Shell, XFCE4’s notification daemon).  Under Mac OS X 10.7 and
further, you need to work with some system APIs, and that may not be
easy, but possible (eg. https://github.com/alloy/terminal-notifier for
Ruby).

But Windows?  GOOD LUCK!  The following options exist, none of which
is easy to implement, and one of which is not usable with most
clients:

a) Toast Notifications in Windows 8/Server 2012, which is not a
   popular platform and may require quite a lot of magic in terms of
   coding and else (VS2012);
b) Create a tray icon and do a balloon (2000 and up?, definitely in XP);
c) Create your very own Windows toast notifications framework.

The command you are looking for is: which python3

You can link it to /usr/bin/python3.  There should be no problem when
you do this.

That should install it for the Python 2.6.6 you have, and possibly
under the name `python-pip` because of various shenanigans in the
redhatesque repos.

Get ez_setup.py and get-pip.py, and run them with the desired Python.

We could report abuse to his server, eternal-september.org[0].  I
tried to do this, but they wanted fancy usenetty headers, and I am not
equipped to get them.

Now, we can try reporting for (a) abusive trolling; (b) excessive

(if I understand the Breidbart Index correctly, we might have to wait
for this, at least two emails to be precise)

The answer likely is *you are not allowed to do this*.  It’s up to the
user to set it.

Unless you are the user, and want to have the packages you install go
to a place desired by you, then the --prefix parameter may be of help
(although you are better off by using a virtualenv which makes it

For some people, it might be a lot.  Why waste money on something,

So, you have four options:

b) use PyQt4 and Qt@Digia, pay £350/£420 + £??? and be sane;

d) use PyQt4 and Qt@Project, pay £350/£420 and look like a hypocrite.

While printing the string, instead of the list/seeing the list’s repr,
Python shows a nice human-friendly representation.

>>> s=[u'\u0105\u017c\u0119\u0142\u0144']
>>> s
[u'\u0105\u017c\u0119\u0142\u0144']

u'\u0105\u017c\u0119\u0142\u0144'
>>> print s
[u'\u0105\u017c\u0119\u0142\u0144']
>>> print s[0]
ążęłń

However, that is only the case with Python 2, as Python 3 has a
human-friendly representation in the repr, too:

>>> s=[u'\u0105\u017c\u0119\u0142\u0144']
>>> s
['ążęłń']

It depends.  Some other frameworks (like Flask) also offer auto-reload
in debug mode — auto-reload can be bad for you and is not supported by
production environments, in which uWSGI (in Emperor mode if
possible/makes sense on Windows) and nginx is the best solution
around, and auto-reload isn’t supported (for good reasons, as
mentioned before).

But you have a way to hide it for people whose clients do support
that.  Simply, instead of signing your letters with “JM” yourself and
having your employer add this spam, simply have your mail client add
the sequence below as your signature.  Some clients offer adding the

The “magical” sequence is: -- \nJM

This can also be seen with a (monolingual) dictionary.  For example:
https://www.google.com/search?q=define+fly (that’s actually from the
New Oxford American Dictionary):

fly, verb: 1. move through the air under control. 2. move or be hurled
quickly through the air.

Those could be valid docstrings (if sheep could fly, of course…) — so,
in other words, act as if you were writing a dictionary and not Python
code.

The path to your cache directory is incorrect.  I suggest using
absolute paths (eg. /home/user/packages) instead of relative paths,
which is likely what caused this issue.

Actually, you could even tar up that entire repo (or even get a nice
ready tarball from GItHub) and you will get something usable with pip.
 For example, we in the Nikola project
(https://github.com/getnikola/nikola) upload the GitHub tarballs to
PyPI because we ship 99.9% of our tree anyways and hiring `setup.py
sdist` would be a waste of time (and would produce two
almost-identical-but-not-quite tarballs).

It’s heavily outdated, and that IS the cause of your problem.  pip 1.5

You need cookies.  In order to do it, simply use sessions instead of
the “global” API.  Code:

import requests

payload = {'username': 'username', 'password': 'password'}
session = requests.Session()
r = session.post("http://www.tt-forums.net/ucp.php?mode=login",data=payload)
sidStart = r.text.find("sid")+4
sid = r.text[sidStart:sidStart+32]
parameters = {'mode': 'login', 'sid': sid}
r = 
session.post("http://www.tt-forums.net/ucp.php",params=parameters,data=payload)
if "Logout" in r.text: print("We are in")

(for the record, I added the session creation line and replaced
requests. with session. so it uses your session.  This code was not
tested on a real phpBB forum; if everything you coded is correct, it
will work.)

Having lots of humans give support is much better when you have

I personally suggest trying something more popular, like Flask,
Bottle, Pyramid, or Django (though it’s quite big and complicated).
Lots of tutorials exist for those.  There are big, vivid communities
offering help and support.  You can often find good solutions for
popular problems (like user accounts) without reinventing wheels.
Flask is the easiest option, and it’s very popular.

This returns a string, not a list.  Moreover, lines.extend() is
useless. Replace this with:

lines = f.readlines()
return lines[11:]

Splitting one character will turn it into a list containing itself, or
nothing if it was whitespace.

This is not what you want it to be — it’s only a single letter.

Thus it fails here, because ['n'] has just one item, and not nine.

“L” is actually valid, and so is “l”.  This happens mainly because
humans (and computers) tend to write “1 l” (one liter, one-ell) in a
way that makes it harder to distinguish (becoming eleven or ell-ell),
especially if you don’t include the space (which is invalid).

Nitpick time!  (because we all love it so much!)

Π¹ = U+03A0 GREEK CAPITAL LETTER PI
π² = U+03C0 GREEK SMALL LETTER PI
∏³ = U+220F N-ARY PRODUCT

“If you can type an N-ARY PRODUCT, you can type a GREEK SMALL LETTER
PI, unless there’s something very weird going on.”

…like, the user is in the past and is using ISO 8859-7 (instead of a
21st-century encoding, like UTF-8).  An encoding which has support for
Π¹ and π², but not for ∏³… (of course, this assumes that, if we add
those new characters into python, we allow any encoding, somehow.)

That’s not too weird, other than the ancient encoding being used.
(though that’s a bit less weird on Windows, but that’d be
Windows-1253.)

Oh: and speaking of fancy Unicode characters that are worthless
~duplicates, spot the difference here:

µ μ

If you are lucky enough (and, luckiness may involve reading this
e-mail in Helvetica (not Neue though) on a Mac), you can clearly see
that they are different.  If you are using a font that does not
differentiate them, you may think they’re the same.  If you ask some
intelligent software (like `unicodedata.name()` in Python), you’ll
quickly find out the first is MICRO SIGN, and the other is GREEK SMALL
LETTER MU.  Such craziness is what makes Unicode Unicode.

It requires having pytz, or dateutil, in order to get timezone
objects*.  You can also create those objects yourself, but that’s
tricky — and you SHOULD NOT do time zones on your own and just use
something else.  Why?  See [0].

Example with pytz:

# Necessary imports
import pytz
from datetime import datetime

# the timezone in this example is Europe/Warsaw — use your favorite one
tz = pytz.timezone('Europe/Warsaw')

now = datetime.now(tz)
# Note I’m not using the tzinfo= argument of datetime(), it’s flaky
and seemingly uses a historic WMT (+01:24) timezone that is dead since
1915.
future = tz.localize(datetime(2014, 12, 24))

# And now you can happily do:

delta = future - now

# and you will get the usual timedelta object, which you can use the usual way.


###

* pytz ships the Olson tz database, while dateutil maps uses your
system’s copy of the tz database (if you are on Linux, OS X or
anything else that is not Windows, really) or maps to the Windows
registry.  Use whichever suits you.

You are trying to use tools that enforce a set of rules, one of which
is “use 4 spaces per indentation level”.  If you don’t agree with this
rule, simply don’t use tools that enforce these rules.  It’s that
easy.

But note, that E111 is “indentation is not a multiple of four”.  Which
you are never going to listen to anyways if you want 2 spaces per
indentation level.  If you *really* want to do 2 spaces (and look
weird), then just ignore that.

You’re using a regular string.  In which backspaces can be used in
escapes.  \t is one of those escapes, it is the tab character.  In
order to fix, add the letter "r" before the opening quote.  Like this:

> plt.title(r'$\mathrm{poles}$ $(\times)$ \

The 99-characters rule does not apply for the stdlib.  And outside of
the stdlib, PEP 8 is not mandated by Python (but it might be by the
project leader or similar entities).  If someone wanted long lines,
then they could do so ALL THE TIME.

Jinja2 is a standalone templating engine, something like Smarty for
PHP.  And Flask is a microframework, which adds on top of Jinja2 (not
mandatory) and Werkzeug (another Pocoo project) to make a nice and
easy webdevelopment base.  IMO it is the best choice in terms of
microframeworks.

But microframeworks are, as the name states, micro.  The big
frameworks include tons of abstractions and fancy features.  Some
people may like them, others may not.  (Those features can obviously
be implemented in the microframeworks on one’s own or through existing
open-source code.)

How are you running uWSGI?  On sane (non-Windows) OSes, I recommend
using the uWSGI Emperor, which will protect you from your website
going down when something crashes.  You run the Emperor through your
OS’s init system (e.g. upstart in Ubuntu, systemd in many others).

There are no rules.  You should use common sense instead: if the

Use split() and join() methods of strings, along with slicing.  Like this:

fullstring = """foo
bar
baz"""

sansfirstline = '\n'.join(fullstring.split('\n')[1:])

The last line does this:
1. fullstring.split('\n') turns it into a list of ['foo', 'bar', 'baz']
2. the [1:] slice removes the first element, making it ['bar', 'baz']
3. Finally, '\n'.join() turns the list into a string separated by
newlines ("""bar
baz""")

I can point you to “find a sysadmin that will work for you and fix

It looks like you are accusing someone of doing something without any
proof whatsoever.  Would you like help with the fallout of the lawsuit
that I hope Mark might (should!) come up with?

Speaking of “try again”, I doubt it would be hard…  As long as a FTP
daemon is running somewhere (and you clearly do not know better); or
even you have a SSH daemon and you do not know better, an attacker
can:

a) wait for you to publish your password yet again;
b) get you to download an exploit/keylogger/whatever;
c) brute-force.

Well, considering it’s unlikely you actually have a long-as-shit
password, (c) is the best option.  Unless your password is very long,
in which case is not.

I’m also wondering what language your password is in.  If you actually
used a Greek phrase, how long will it take you to get locked out due
to encoding bullshit?

Did you know that you just lowered the amount of characters an

(UTF-*/ISO-8859-7) to just 95?  No?  Congratulations anyways, Nikos!

Or the statement is a blatant lie and was meant to be

mysql_password is not account_password

as they have the same value, but are set independently.  (too much Python Ale…)

It would require Postgres around people’s (or at least packagers’)
systems, and it often gets messy when we have such requirements.
Psycopg2, the most popular binding, is licensed under LGPL3 + Zope (or
such, there is a little mess here) which MAY pose a problem (IANAL
though).  Also, Postgres is much harder to configure than MySQL,
especially if you have no experience or an asshole OS.  Moreover, the
stdlib is where packages come to die.

So, instead of this, maybe we should work on getting psycopg2 to the
top result on Googling “python sql”, or even “python mysql” with an
anti-MySQL ad? (like vim was doing some time ago on Googling “emacs”)

We should also educate people on how PostgreSQL works with a nice,
human-friendly tutorial.  Especially in some non-standard things and
things that differ between PostgreSQL and MySQL — like how to make an
auto-incrementing ID field (use sequences), or how PostgreSQL arrays
work, among others.  The wiki (that nobody reads anyways) could also
use some marketing fixes.

I have a screenshot:

Dropbox claims it was taken at around 2011-03-19T11:32:24Z.  Earlier
today, the exact same ad appeared while searching for “vim”, but not
“emacs” (why bother when you are the first hit for this query
anyways?).

Now, for statistics, how many hits it got, or whatnot — go ask the Vim
developers.

You indented the wrong thing.  You put your if/else statement in a
non-standard way (which works, but is discouraged).  Also, you ended
the first line with a semicolon (same case).  So, the proper code
would be:

a=1
if a==1:
print(1)
else:
print(0)
wait = input("press key")

(I resisted the urge to add spaces around `=` and `==`, something most
people want you to do.)

Depends on what do you want to calculate.  Also, note that Python is
liked by the scientific community to use for calculations.  This might
be a hint.

Yes.  Although most people in the Python community dislike the
old-style “CGI” and use “web apps” instead.  They are also connected
with a different philosophy, for example we do not store .py files in
/cgi-bin/, we never expose our .py files and put it somewhere else on
the system and let the web server act as a proxy to a WSGI server
(gunicorn/uwsgi).

Yes, but you need to install additional libraries for that.

Definitely possible, but might take you a bit of work and knowledge of
Windows internals (go ask Google).

On Linux, the `nuitka` script would be run.  Things in $PATH tend not
to have an extension, and you don’t need one to run Python.  (you
can’t import files that don’t end in .py, though)

This is a very fancy way of running Nuitka in the local python
interpreter, with all the arguments.  For example, this:

C:\Python27\Scripts\nuitka.bat foo bar

will make the script run:

C:\Python27\python C:\Python27\Scripts\nuitka foo bar

This is to make Windows users’ life easier, to provide them
executables that work just as `nuitka` (and not `nuitka.py`).
However, a more modern method than the one used here is setuptools
entrypoints, which produces a nicer .exe file.

Either (a) pypi, or (b) you were offline when trying to install.

Also, you generally want to use get-pip.py instead, it will also get
you pip in addition to setuptools:

And yet, you did not give up an even more insane line length limit, in
e-mail.  The longest line in your original message is a measly 57
characters long.  The median line length is 46 characters.  Which is
pretty insane, and ultra-hard to read.  You can do more in e-mail.

That's the standard, [RFC 5322][]; the exact same quote appeared back
in [RFC 2822][].  However, many places actually want you to use a bit
less; common values include 70 or 72.  But still, it is MUCH more
roomy and readable than the value you use.

Here are the line lengths in the original message:

[47, 45, 45, 46, 46, 47, 45, 5, 46, 43, 46, 47, 47, 49, 31, 57, 52,
 34, 42, 23]

[RFC 5322]: http://tools.ietf.org/html/rfc5322#section-2.1.1
[RFC 2822]: http://tools.ietf.org/html/rfc2822#section-2.1.1

Please don’t learn from this link.  It’s from 2001.  You should learn
from modern documentation: https://docs.python.org/ (if not running
3.4.x, change the version in the top)

You also should not read the language reference, it’s meant for people
who really care about what’s under the hood.  The official tutorial is
better for learning: https://docs.python.org/3/tutorial/index.html

Both characters (' and ") are interchangeable, the only difference
being the one you need to escape if you want to use in a string:
"you're" vs 'you\'re', and the other way around.

Also, please read the Python tutorial[0] before getting into bigger
things, and please don’t mix documentation versions.  If you were to
read the tutorial, you’d quickly find out, that

I personally parse those lines as “sent from my iPhone, which has an
on-screen touch keyboard, and it’s harder to type on it”.

Corporate lawyers for the win!  99.9% of people who send e-mail with
this line are forced to do so by their corporation’s legal department.

Also, the correct solution for all those is getting a sane client that
can hide quotes and signatures.  Like Gmail (which defaults to
top-posting, but fixing this is one click per message away*).  And if
someone brings the “people need to download it anyway” argument: it’s
2014, people: hard-drives are large nowadays (or you can just use
IMAP) and if you’re paying $100 per kilobyte, you’re doing it wrong
and should not be online in the first place.

* trickier on mobile, though.

There’s your problem: video tutorials are the most evil invention of
the human race.  It’s hard to learn from them.  You should not watch
any — use text tutorials instead.

“win32” is the name given to the Windows API as of Windows NT 3.1 and
Windows 95.  The “AMD64” part in parentheses tells the truth, that
you’re actually running the 64-bit version (which can cause problems,
though — it’s better to use the 32-bit version, IMO)

Yes, exceptions do exist. But most video tutorials are produced by people
without enough knowledge, and people that should not be working on
educational material. This is especially visible in videos about basic
things: they can be produced by just about anyone with a microphone — which
never leads to anything good. (In order to be more precise, I'd have to be
politically incorrect.)

This is one of the issues: you can easily mess up 32-bit and 64-bit,
and not even notice that (AppVeyor had an issue with that lately —
they switched python to 64 but left VC++ as 32).

It’s also slightly easier to find pre-made binaries for 32-bit than
64-bit.  In general, life in 64-bits on Windows is kinda hard, for
everyone involved.
