I contacted Visual Studio 2019 support about this and they referred me to
this site, but I'm not sure this is a bug or not
(https://github.com/python/cpython/issues/new?assignees=

I'm not new to python, but I'm new to cpython and visual studio.  I need to
install Visual Studio 2019 and get the PCBuild/get_external.bat file up and
running.  I have python 3.10.4 installed.  I tried installing the Community

it's supposed to create a folder in my python directory called PCBuild with
that bat file in it and it doesn't.  I've searched my C drive for PCBuild
and get_external.bat and nothing is found.  

 

I've executed this command and from what I can tell, I have installed the
correct version of Visual Studio:

 

python -c "import sys; print(sys.version)"

Function to Print a nicely formatted Dictionary or List?

Hi,

Before I write my own I wondering if anyone knows of a function that will print

By nicely formatted I mean not all on one line!

It's called "pretty-printing". Have a look at the 'pprint' module.

I might add the note that there was a recent thread on the Discuss board
about options for styling the pprint output (okay, it was me that
started that one...) - you can choose indent and compact (compact is the
not-all-on-one-line flag) but there might be some other choices missing.
haven't gotten around to following up on that...

Re: How to test characters of a string

[Avi Gross via Python-list]

Dave,

Sometimes a task is done faster by NOT programming anything in any language!

Not only have you spent a lot of your own time but many dozens of messages here 
have dragged in others, who gain nothing ;-)

The domain you are operating in seems to have lots of variants in how the 
titles are stored as names and you keep finding new variants. Yes, if your goal 
is to use this as a way to learn more in general about Python, clearly it may 
meet that goal!

Contrary to what I (and some others) said earlier, it may be time to consider 
regular expressions and other heavier artillery! LOL!

I do not plan on sticking with your twists and turns but will quickly address 
your variants.

Sides that come in two's like records are presumably limited to using A and B 
in your example. But multiple disks connected can mean the digit(s) following 
can have double digits or even more. Your python code may have to contain lots 
of functions you create that match some pattern and return some value and 
perhaps other functions that know how to convert from that format to a common 
canonical format of your own so they can be compared.

Your main code may need to try them in various sequences till it finds a match 
and so on.

But when you are done, in what format do you save them? The original or your 
minimal? 

Still confusing to me, as someone who does not give a darn, is the reality that 
many songs may have the same name but be different as in a song from Sinatra 
when he was young and a later recording  with a different orchestra or by a 
Sinatra imitator. They may all be titled something like "New York, New York" or 
"NEW YORK -- NEW YORK" which your algorithm folds into the same characters.

So I am guessing you also need to access other data about the person who sings 
it or what year it was released to make comparisons. At some point you may want 
to create or borrow some sort of class/object that encapsulates your data as 
well as methods that let you do things like make a canonical version of the 
Title and then a way to ask if Object A is reasonably equal to object B might 
happen if you define a function/method of __eq__ for that class.

It might take you years and need periodic refining as you encounter ever more 
varied ways people have chosen to label their music, but so what? LOL!

Humor or sarcasm aside, your incremental exploratory method reminds me why it 
is a good idea to first scope out the outlines of your problem space and make 
some key decisions and write out a fairly detailed set of requirements before 
seriously making more than prototypes. You might get very different help from 
people if they understood that your first request was far from complete but 
only one of many that may better be worked on some other way.
And I wonder if you did any search of the internet to see if anyone had done 
anything similar in Python (or another language) that may handle parts of what 
you need before asking here. I note lots of people who come with what they 
consider a good programming background have to adjust to aspects of languages 
like python as what they know is in some ways wrong or inadequate in a new 
environment.

Hesitantly, because this is the Python mailing list, I claim (a) ':' is
simpler than r'([^:]*):([^:]*):(\d+):(\d+):([^:]*):([^:]*):(.*)$', and
(b) string.split covers pretty much the same edge cases as re.search.


Ah, but you don't catch the be numeric of fields (0-based) 2 and 3! But
agreed, it's not the best of examples.



Yes, that is a simplistic example, since the : can't even be quoted to 
appear in that format (which would require higher-order parsing than a 
simple split)


Fortunately, the OP has just given another requirement to recognise 
different patterns, and now it went into a direction where it will 
become quite ugly if you avoid REs or any other pattern matching tools.


This is also the main reason I suggested REs initially - often if you 
see other patterns in the data, you can easily adapt a RE solution, 
whereas you'll have to write the thing from ground up anew if you do it 
manually.

Re: Function to Print a nicely formatted Dictionary or List?

[Avi Gross via Python-list]

Dave,

Despite your other programming knowledge, I suspect you think this is the forum 
where people come to be tutored. Try here:

https://mail.python.org/mailman/listinfo/tutor

Yes, there are plenty of pretty printers available and you can build your own 
function fairly easily. A module like pprint may have what you want in 
pprint.pprint()  but you can write a function for yourself that takes a  
dictionary and loops through items and prints them one per line and, if you 
feel like it, also prints how many items there are and your own custom touches 
such as doing them alphabetically.
Consider using a search engine before posting. Throw in a few words like 
"python pretty print dictionary function" and refine that if it does not get 
you immediate results. It is free and easy and does not waste time for so many 
others who already know or don't care.
And consider reading a few books perhaps designed to teach python to people 
with some programming experience or taking a course on something like COURSERA 
as a part of your learning process and not depending on volunteers so much. 
Much of what you are asking is covered in fairly beginner and intermediate such 
books/courses.

I think I am now going to ignore messages from you for a while. Signal to noise 
ratio ...

Now you're getting into the complexity that is better handled by REs 
than by individual character examination.

The first of your formats matches the RE

\d-\d{2}

(one digit, - two digits). Anchor that to check for a match at the 
beginning.


The second one matches

(A|B)\d-

As long as one digit is enough. What is your goal, to extract these 
numbers or to strip them? Regexes can do both relatively easily.

For small outputs, pprint uses a single line.  For larger outputs, it
inserts newlines. It's intended to be human-readable more than
machine-readable.

Here's how I fixed that problem:

  https://github.com/GrantEdwards/hybrid-inews

I read this "group" using slrn pointed at gmane.comp.python.general,
on the NNTP server news.gmain.io. When I post to this group from slrn,
it gets e-mailed to the regular mailing list address. Other gmane
"groups" get posts sent via NNTP. slrn is configured to post all
articles via /usr/local/bin/inews (which is the python "inews"
work-alike program above) when connected to news.gmane.io.

How/why people follow mailing lists via actual e-mail is beyond my

Note that JSON output is JavaScript notation, not Python. The `pprint` 
module (which has `pprint` and `pformat` functions) outputs Python 
notation.

If you're just writing for human eyes, JSON is fine, though you will 
want to keep in mind that JSON spells `None` as `null`.

I wonder why Steve changed the name of the environment variable
without supporting the old "PYLAUNCH_DEBUG" name, at least for a
couple of releases. Since 3.11 is still in beta, with the first
release candidate expected in August, there's still time to restore
support for the old name.

Does getenv() confirm that the variable is set?

>>> import os
>>> os.getenv("PYLAUNCH_DEBUG")
'1'

Looks like the variable is now called PYLAUNCHER_DEBUG:
