Yes indeed, there is no need to use a loop since i know the exact
number of items i'am expecting. Thanks you very much for clarifying this
to me:
One last thing i want to ask you:
try:
cur.execute( '''SELECT host, userOS, browser, hits, lastvisit FROM
visitors
WHERE counterID = (SELECT ID FROM counters WHERE URL = %s) ORDER BY
lastvisit DESC''', (htmlpage,) )
except MySQLdb.Error, e:
print ( Query Error: , sys.exc_info()[1].excepinfo()[2] )
else:
data = cur.fetchall()
for host, useros, browser, hits, lastvisit in data:
print ( tr )
for item in host, useros, browser, hits, lastvisit.strftime('%A %e
%b, %H:%M').decode('cp1253').encode('utf8'):
print ( tdcenterbfont color=white %s /td % item )
sys.exit(0)
===
That would be also written as:
for row in data:
print (tr)
for item in row:
print( blah blah blah )
And that would make the code easier to read and more clear, but its
that 'lastvisit' column's value than needs formating,hence it makes me
use the above syntax.
Is there any simpler way to write the above working code without the
need to specify all of the columns' names into the loop?
You can write:
for row in data:
print (tr)
row = list(row)
row[-1] = row[-1].strftime(...)
for item in row:
print( blah blah blah )

for line in open(/home/john/myfile):
The line above opens the file in read-only mode. It's not possible to
make changes to the file if you only open it in read-only mode. So no
this code is not modifying the file. It is, however, slightly better
to write the above as
with open('/home/john/myfile') as fin:
for line in fin:
# stuff
This is better as the with statement handles errors better than just
calling open directly.
linecount = linecount + 1
if linecount == 1: # ignore header
continue
Another way of achieving this would be to do:
headerline = fin.readline()
for line in fin:
# No need to worry about that header line now

The only complication I'd see would be the reader bombing out because the writer process is in the middle of writing. A quick test on WinXP showed that it's possible to continue to write to a file that another process has open for reading (this shouldn't be an issue on POSIX OSes; Win32 can be a bit more fascist about sharing files, especially if they're both open for writing). However, that doesn't alter the data written, so all it takes is just re-running the reader process. -tkc -- http://mail.python.org/mailman/listinfo/python-list

Nothing wrong with learning Python on your own, but if you feel you haven't made much progress in a year, perhaps your approach is inadequate, or perhaps you need more discipline in applying it. Or maybe you actually know more than your realize. If you could be specific in some concept that escapes you, maybe we could give some specific help. First, your background. Are you fluent in any other languages? Have you any college training in any particular computer skills? Do you use them in your work, or what? Next, what have you been doing to actually try to learn? Have you worked through a tutorial, and I mean really worked through it, writing programs for every exercise, not just read it, and hoped it'd stick? If so, which tutorial? Finally, what version of Python are you learning, and on what OS can you play? Do you actually have it installed, or is this book learning?

RE: Reading data from 2 different files and writing to a single file
Hi, as many others I am not exactly sure what the purpose of your code really is. However, if what you´re trying to do here is to take one line from f1, one line from f2 and then write some combined data to nf, it is not surprising that you're not getting what you expect (the main reason being that your for loops are nested, as pointed out already). In that case, a much cleaner and less error-prone solution would be iterator-zipping, leaving you with just one for loop that is easy to understand: for l,s in zip(f1,f2): # now l holds the next line from f1, s the corresponding line from f2 do_yourstuf() write_output() if your files are large, then in python 2.x you should use: import itertools for l,s in itertools.izip(f1,f2): do_yourstuff() write_output() The reason for this is that before python 3 zip gathered and returned your results as an in-memory list. itertools.izip and the built-in python 3 zip return iterators.

I have issues installing pycrypto (and thus fabric) with pip
I'm not sure this is the right place for this but I'm don't know where else to
put this.
I want to give fabric a try (as recommended here:
http://www.jeffknupp.com/blog/2012/10/24/starting-a-django-14-project-the-right-way/).
Installing fabric results in two dependencies (paramiko and pycrypto) being
installed as well. All is dandy until it is time to install pycrypto.
A bit of searching reveals this in the documentation:
Package tools
We strongly recommend using pip to install Fabric as it is newer and generally
better than easy_install. However, a combination of bugs in specific versions
of Python, pip and PyCrypto can prevent installation of PyCrypto. Specifically:
Python = 2.5.x
PyCrypto = 2.1 (which is required to run Fabric = 1.3)
pip 0.8.1
When all three criteria are met, you may encounter No such file or directory
IOErrors when trying to pip install Fabric or pip install PyCrypto.
The fix is simply to make sure at least one of the above criteria is not met,
by doing the following (in order of preference):
Upgrade to pip 0.8.1 or above, e.g. by running pip install -U pip.
Upgrade to Python 2.6 or above.
Downgrade to Fabric 1.2.x, which does not require PyCrypto = 2.1, and
install PyCrypto 2.0.1 (the oldest version on PyPI which works with Fabric 1.2.)

WLAN tester
I'm looking to make a WLAN tester for a manufacturing test. Something that could send and receive a bunch of files and measure how long it took. I would repeat this a number of times for a device under test and then use some metric to decide pass/fail and create a report.

Depending on what's at the far end of your connection, you may not need to do much at all. For example, if you have an ftp server, check out http://docs.python.org/2/library/ftplib.html in the standard library. Since you're doing performance testing, be aware that it's quite tricky to get meaningful results.For example, some connections have a satellite link in them, and thus have very long latency. A simple protocol will go very slowly in such a case, but most downloaders will open multiple sockets, and do many transfers in parallel. So you could either measure the slow way or the fast way, and both numbers are meaningful. Of course, it's more than a 2-way choice. Some protocols will compress the data, send it, and decompress it on the other end. Others (like the one rsync uses) will evaluate both ends, and decide which (if any) files need to be transferred at all. I believe it also does partial file updates if possible, but I'm not at all sure about that.

The London Python Group:Switch to Python 3… Now… Immediately - February 12th
Russel Winder gives numerous reasons why now is the time for you to switch to Python 3 RIGHT NOW! With Python 3.2 and even more with Python 3.3, Python 3 became usable for release products. Indeed given the things that are in Python 3 that are not being back-ported to Python 2, using Python 3 should probably be considered mandatory for all Python use. Certainly for new projects, and 2 → 3 ports for all extant codes. In this session we will investigate some of the issues, especially those relating to handling of concurrency and parallelism, and in particular concurrent.futures. Some material on CSP will almost certainly creep into the session.

That would be a relatively consistent metric, whereas if you try using FTP you'll run into issues, as already noted, where disk read/write speed and details of your FTP server implementation like compression or multiple network connections affect the result significantly. -- Robert K.

[issue17061] tokenize unconditionally emits NL after comment lines blank lines
New submission from Thomas Kluyver:
The docs describe the NL token as Token value used to indicate a
non-terminating newline. The NEWLINE token indicates the end of a logical line
of Python code; NL tokens are generated when a logical line of code is
continued over multiple physical lines.
However, after a comment or a blank line, tokenize emits NL, even when it's not
inside a multi-line statement. For example:
In [15]: for tok in tokenize.generate_tokens(StringIO('#comment\n').readline):
print(tok)
TokenInfo(type=54 (COMMENT), string='#comment', start=(1, 0), end=(1, 8),
line='#comment\n')
TokenInfo(type=55 (NL), string='\n', start=(1, 8), end=(1, 9),
line='#comment\n')
TokenInfo(type=0 (ENDMARKER), string='', start=(2, 0), end=(2, 0), line='')
This makes it difficult to use tokenize to detect multi-line statements, as we
want to do in IPython.
In my tests so far, changing two instances of NL to NEWLINE in this block
(lines 530 533) makes it behave as I expect:

[issue17062] An os.walk inspired replacement for pkgutil.walk_packages
New submission from Nick Coghlan: I recently had occasion to use pkgutil.walk_packages, and my immediate thought was that it would have been a lot easier for me to use if it worked more like os.walk with topdown=True, producing tuples of (pkg, subpackages, modules) pkg would be the package object at the current level (None for the top level) packages would be a dictionary mapping fully qualified module names to loader objects for the subpackages (i.e. subdirectories) modules would be a dictionary mapping fully qualified module names to loader objects for every submodule that wasn't a subpackage As with editing the subdirs list with os.walk, editing the packages dictionary with this new API would keep the iterator from loading that subpackage and avoid recursing into it (this is the part I wanted in my current use case).

[issue17064] Fix sporadic buildbot failures for test_mailbox
New submission from Jeremy Kloth: Attached is an attempt at fixing the sporadic failures of test_mailbox on the AMD64 Windows buildbot. It fails due to access errors on some directories which leads me to believe the helper functions in test.support should fix the problem. -- components: Tests files: test_mailbox.diff keywords: patch messages: 180862 nosy: jkloth priority: normal severity: normal status: open title: Fix sporadic buildbot failures for test_mailbox versions: Python 3.3, Python 3.4, Python 3.5 Added file: http://bugs.python.org/file28882/test_mailbox.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17064 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17065] Fix sporadic buildbot failures for test_winreg
New submission from Jeremy Kloth: test_winreg fails sporadically on the AMD64 Windows buildbot. Looking at the test, it appears that concurrent runs of the test would fail if different processes attempted to modify the test key at the same time. The attached patch resolves this by using a per-process unique test key name using the process ID. -- components: Tests files: test_winreg.diff keywords: patch messages: 180863 nosy: jkloth priority: normal severity: normal status: open title: Fix sporadic buildbot failures for test_winreg versions: Python 2.7, Python 3.2, Python 3.3, Python 3.4, Python 3.5 Added file: http://bugs.python.org/file28883/test_winreg.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17065 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17064] Fix sporadic buildbot failures for test_mailbox
R. David Murray added the comment: I think the support functions just ignore errors. Isn't this going to continue to leave garbage on the buildbot filesystem without fixing the underlying problem? I wonder if this is a variation on the usual Windows access errors, in which case perhaps that is the best we can do... -- nosy: +r.david.murray ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17064 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17063] assert_called_with could be more powerful if it allowed placeholders
Michael Foord added the comment: Yes there are definitely room for documentation improvements. And, yes - pulling the args out from some_mock.call_args boils down to doing the matching by hand. You only do it when you *want* to do the matching by hand. Your use case I would write: from mock import Mock, ANY ... my_mock(1, someobj(), bar=someotherobj()) my_mock.assert_called_with(1, ANY, bar=ANY) args, kwargs = my_mock.call_args foo = args[1] bar = kwargs['bar'] self.assertIsInstance(bar, someobj) self.assertIsInstance(foo, someotherobj) It's a *little* cumbersome, but not something I do very often and not much extra code. I'm not sure that having assert_called_with return objects is an intuitive API either. (And having to specify tuple indices in a call to ANY is a bit odd too.) Custom matchers that do the comparison in their __eq__ method would be another possibility: class IsInstance(object): def __init__(self, Type): self.Type = Type def __eq__(self, other): return isinstance(other, self.Type) my_mock.assert_called_with(1, IsInstance(someobj), bar=IsInstance(someotherobj)) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17063 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17064] Fix sporadic buildbot failures for test_mailbox
Jeremy Kloth added the comment: Actually, the support functions (as of 3.3) attempt to work around the access errors. They attempt to wait (to a point) for a successful operation before returning to the caller. See issue15496 for details. It is usually the case that the previous operation has not yet finished as to the cause of the access error. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17064 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue4590] 2to3 strips trailing L for long iterals in two fixers
Fábio M. Costa added the comment: I believe that since this change the 2to3 documentation is outdated. http://docs.python.org/2/library/2to3.html#2to3fixer-long http://docs.python.org/2/library/2to3.html#2to3fixer-numliterals http://docs.python.org/3/library/2to3.html#2to3fixer-long http://docs.python.org/3/library/2to3.html#2to3fixer-numliterals They could be updated to something like this: long Renames long to int. Check `numliterals` if you want to strip the L suffix on long literals. numliterals Converts octal and long literals into the new syntax.
