what is the easiest way to install multiple Python versions?
Hi, (sorry for cross-posting) A few days ago I needed to check whether some Python code ran with Python 2.6. What is the easiest way to install another Python version along side the default Python version? My own computer is Debian Linux 64 bit, but a platform-independent solution would be best.

This project is dead -Deadsnakes -Anaconda -Tox? I only know this is as a cross-version/implementation test runner -Vagrant. This is what I eventually did, and this was very simple. I ran Ubuntu 10.0.4 LTS, which uses Python 2.6, and used Vagrant SSH to run and check my code in Python 2.6 (and I replaced a dict comprehension with a list comprehension, for example) - ...

I can't really say about job postings, but presumably you've done the searches and found that to be the case. But there are plenty of jobs around that don't specifically name the technologies you have to use. If you're asked to create a web site from nothing, it doesn't much matter what you use, as long as you get the job done. The other thing to note is that job postings and resumes form a feedback loop. Why bother mentioning Flask on your resume, if no employers ever ask about it? Why bother looking for Flask programmers, if nobody ever mentions having experience with it? My personal recommendation: Stick to Flask. It's a good system, and there's no reason to run away from it. (That said, I've yet to use Django, and I've used Flask for exactly one web site, which is why I didn't respond to you when you first posted.)

After that, just look at exactly what packages you're still lacking. You may well find that you don't have all the dependencies for all Python modules, as some of them might not be included in a basic apt-get install python installation; the solution is a bit more apt-get build-dep work, or some manual hunting down of dev packages (which may well be easier in some situations).

My intention is if either of the conditions are true the loop should break.
But the condition after 'or' doesn't seem to evaluate.
A general rule of programming (be it Python or any other language) is to
break up complicated code into smaller pieces which can be understood
and tested in isolation. Your 'while' condition is kind of hairy.
There's a couple of complicated expressions, a logical conjuction, and
two different negated comparisons. That's a lot to understand all at
once.
I would factor that out into a little function:
---
def is_yes(answer):
if answer.lower() == 'yes':
return True
if answer.lower()[0] == 'y':
return True
return False
while is_yes(ans):
ans = input('Do you like python?')
---
Now, you can play around with your is_yes() function in an interactive
session and see what it returns for various inputs, in isolation from
the rest of your program:
print is_yes('y')
print is_yes('yes')
print is_yes('no')
print is_yes('you bet your sweet bippy')

Yes..however, the second part of the or condition doesn't get evaluated.
So if I enter a 'y' - I expect the second part to evaluate and the loop to
break - but that doesn't seem to happen.
Break it down into separate parts and have a look at what's happening.
while ans.lower() != 'yes' or ans.lower()[0] != 'y':
ans = input('Do you like python?')
print(ans.lower() = {!r}; first cond = {!r}, second cond {!r},
disjunction {!r}.format(
ans.lower(), (ans.lower() != 'yes'), (ans.lower()[0] != 'y'),
(ans.lower() != 'yes' or ans.lower()[0] != 'y')
))
The while loop will continue so long as the disjunction is True. See
what it's actually doing.
This is fundamental Boolean logic, a basic skill of programming.
You're going to need to master this. Look at the different pieces, and
get your head around what the 'or' operator actually does.

How to install and run a script?
I'm an absolute noob to Python, although I have been programming in several other languages for over 10 years. I'm trying to install and run some scripts, and I'm not having much success. I followed the steps at this site. https://docs.python.org/2/install/ I have Python 2.7.6 Shell. If I type this: python setup.py install I get this: SyntaxError: invalid syntax If I try this: setup.py beautifulsoup I get this: SyntaxError: invalid syntax If I got to File Open . . . . navigate to a folder and open the setup.py file and hit F5 . . . . it looks like it runs, but I can't tell what it does for sure, and then nothing works after that.For instance, I downloaded something called 'Flask'. I put that folder in my Python27 folder, and typed 'pip install Flask' and I keep getting errors. Any idea how to run a simple program??? -- https://mail.python.org/mailman/listinfo/python-list

The commands you're looking at need to be run from your regular shell; I'm guessing you may be on Windows, so that would be the command prompt (cmd.exe). But rather than playing with setup.py directly, you should now be able to use pip, which is also run from the command line: C:\pip install flask C:\\python27\Scripts\pip install flask The first version works if you've added the appropriate directories to your PATH, the second is where the executable is actually found.

The intention is to loop forever until the victim breaks down and accepts
that they like Python, by entering yes or y. I'm pretty sure that
entering yellow or you've got to be kidding should not break the loop.
When you have multiple clauses in the condition, it's easier to reason about
them if you write the clauses as positive statements rather than negative
statements, that is, something is true rather than something is not
true, and then use `not` to reverse it if you want to loop *until* the
overall condition is true.
When checking for equality against multiple values, instead of:
x == a or x == b or x == c
it is usually easier to use `in`:
x in (a, b, c)
So we have:
# loop so long as the victim answers yes or y
while ans.lower() in ('yes', 'y'):
ans = input('Do you like python? Well, do you?')
# loop until the victim answers yes or y
while not (ans.lower() in ('yes', 'y')):
ans = input('Do you like python? Well, do you?')
both of which work fine if the user stays mum by entering the empty string.
You can also write:
while ans.lower() not in ('yes', 'y'):
ans = input('Do you like python? Well, do you?')
if you prefer. In my opinion, that's the most readable version of all.
One last note: if you are using Python 3.3 or better, you can support
international text better by using the casefold() method rather than
lower(). In this case, it won't make a difference, but the technically
correct method for doing case-insensitive comparisons is to casefold both
strings rather than lower- or upper-case them.

The error is coming from the __new__ method. Because str is an

or, if one is mere adding a method, do not add __new__ either.

[issue22571] Remove import * recommendations and examples in doc?
Raymond Hettinger added the comment: Many of these (such as collections, collections.abc, decimal, and itertools) use import * as part of the doctest setup and are not part of the generated page shown to users. Also, I don't think you should be aggressive about removing the other example that are visible users. The import * construct is part of the language and will be encountered occasionally. For similar reasons, the decimal module was specifically designed for be easily usable with import * because of the numerous exceptions and rounding flags and constants. There are also some examples such the one in cmd.rst that I put there on-purpose. Changing it would distract from the focus of the example. With respect to Tkinter (and other gui toolkits as well), I believe that import * is a standard or common practice, in part because there are so many widget names names and widget options. Changing the example might make it more pep8-ish but would result in a good deal of clutter that isn't the normal practice. Should we finish the job? Or leave the issue to individual chapter authors? I vote for leaving any changes to the chapter authors who are in a better position to know that they were trying to communicate or who were just setting up the doctests. As discussed above some of the import * are there for a reason. We really need to start thinking of PEP 8 as something we do to our own code rather than something that gets inflicted on other people's code. -- assignee: docs@python - rhettinger nosy: +rhettinger ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22571 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue22616] Allow connecting AST nodes with corresponding source ranges
New submission from Aivar Annamaa: Currently lineno and col_offset attributes in AST nodes have confusing roles. According to documentation they indicate the starting position of node's source text but according to recent developments (#16795) they seem to indicate a position most suitable to use in error messages related to that node (rather narrow goal IMO). Another problem is that currently the AST nodes don't contain any information about the end position of corresponding source text. Therefore it's very difficult to relate nodes with source. One could want to do this for example in advanced graphical debuggers (https://bitbucket.org/plas/thonny) I propose adding new attributes to AST nodes which indicate the corresponding source range. If you want to keep nodes lightweight by default, then you could also introduce a flag in ast.parse for getting these attributes. The range could be given either in token indices or in character positions (or both). This probably needs more discussion. (I would vote against pointers to UTF-8 bytes, as is the case with col_offset currently.) -- components: Interpreter Core messages: 229124 nosy: Aivar.Annamaa priority: normal severity: normal status: open title: Allow connecting AST nodes with corresponding source ranges type: enhancement versions: Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22616 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

But with Lib/test/test_decimal.py, not Lib/decimal.py. The difference between 3.4 and 3.5 is that Lib/decimal.py is large in 3.4, but it is tiny in 3.5. I can easy reproduce this issue because my netbook is too slow. When I wait some time, and then close editor window, there is no traceback. This time is needed to colorize sources in editor window. May be you will reproduce this issue when open very large Python file and then quickly close editor window. If you have no such file, just concatenate large file with itself many times: cp Lib/test/test_decimal.py+Lib/test/test_decimal.py+Lib/test/test_decimal.py+Lib/test/test_decimal.py+Lib/test/test_decimal.py testfile.py What system? I do not reproduce on Win 7 with an Oct 9 build. I believe you will reproduce with enough large file. When? If the command line worked for 2.7 in Jan and fails now, when did it start failing? If the command worked for 3.4 after the Feb patches and fails now, same question. At least with 3.4.0 I don't see this traceback. May it is hidden by the 'can't invoke bind command' error. How? You did not state, but in a later message implied that the file opened in the editor and the problem only happened when you closed, as with the January report. However, the traceback says that the problem occurred during initialization. According to Find in Files, the only call to color_breakpoint_text is that one __init__ call. I therefore do not understand your msg228957 comment The code runs up to self.text.update() in restore_file_breaks() and runs further only after windows closing. Sorry for my ugly English.

Vinay Sajip added the comment: Ronald's change ... changed the stub launcher to no longer do a realpath() on the executable name which means that sys.executable contains the path to the Python stub launcher whether or not in a venv Ronald's change doesn't do a realpath() on the executable name itself, but it *does* do a realpath() on the executable's directory. This seems to be what's causing the problem in Homebrew builds: there are two levels of symlink at play. /usr/local/bin/python3.4 - /usr/local/opt/python3/bin/python3.4 - /usr/local/Cellar/python3/3.4.1_1/Frameworks/Python.framework/Versions/3.4/bin/python3.4 Because of the realpath(), the wrong stub launcher (from Homebrew's perspective) gets pointed to by the environment variable.

[issue15363] Idle/tkinter ~x.py 'save as' fails. closes idle
Terry J. Reedy added the comment: According to the tcl/tk manual, tcl does ~ expansion on non-'old' Windows. However, I cannot tell in what context that could be useful. Trying to save to '~/x.py' fails. The filename is not valid. This might be because there is no HOME since Windows sometimes uses USERPROFILE instead. But it seems that any name with a path separator is invalid. At least on Windows, one must specify the directory my moving to it in the directory part of the dialog. If dirname (passed to tk_getSaveFile as initialdir) is not after the split of self.filename (and I believe it never is), it seems to me possibly a bug that tk_getSaveFile looks for a leading ~ for base (passed as initialfile). But we cannot affect that. Serhiy, your suggesting to check self.filename (full name) instead of base would be correct if tk did not check base after it is split off. But it does, buggy or not. The full name of the project file that failed was something like F:/python/~templete.py. Martin and Serhiy. If I understand correctly, you are both suggesting that '~x.py' should become './~x.py' instead of '\~x.py'. This seems to work equally well. It seems that after ~ processing, the basename gets changed back to and displayed as '~x.py' and saving as such works. You also suggest that at least your version of the escaping should not be limited to Windows. It seems like this might help, and should not hurt, but I would like the latter tested on Linux before I commit. Attached is my patch with both changes. -- stage: needs patch - patch review Added file: http://bugs.python.org/file36887/@tilde.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15363 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue21603] IDLE SaveAs drops the extension in the prompted filename
Ned Deily added the comment: Thanks, Raymond. Upon further investigation, I think you are running into a user-wide behavior of OS X rather than specifically a Tk or IDLE issue. By tradition and by default, OS X tries to hide file extensions in file Open or Save dialogs; this dates back to the days of Classic Mac OS when there was no concept of file extensions. There is a (non-obvious) user preference in the OS X Finder's preferences (Finder - Preferences - Advanced - Show all filename extensions) that appears to control whether extensions are displayed by default in standard Open and Save dialogs in all applications, not just the Finder. (This is with OS X 10.9.x; I believe recent earlier systems behave similarly although the details might be slightly different). When the preference is unchecked (the default), then in Save As dialogs (in IDLE and other apps) a Hide Extension option box appears in the lower-left corner of the Save As popup window and, if enabled, the extension is not displayed as pa rt of the file name. Unchecking the Hide Extension box causes the extension to appear. If the Finder Show all filename extensions advanced preference is checked, then the Hide Extension box does not appear on the Save As popup and the extension is always displayed. I always have the Show all filename extensions preference checked so I forgot it was there and its effect on all file dialogs. My guess is that you will want to have it enabled as well and then you should always see extensions. Note that for the initial Save of a file in IDLE (as opposed to a Save As), Python 3.4 supplies a default extension of .py which is displayed regardless of the Finder preference setting; but Python 2.7 up through the current 2.7.8 does not supply the default. That changes in 2.7.9 as Terry has recently backported the 3.x change to 2.7 (Issue4832, although the commit message for the backport appears in Issue3832 due to a typo). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21603 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue22614] Idle: problem in PyShellEditorWindow.color_breakpoint_text
Terry J. Reedy added the comment: Makes sense now. Large file relative to machine speed + quick close click = close (at least to point of destruction of self.text) before initialization is complete. Hence continued initialization fails. Yes, when closing crashed in Multicall, would not see initialization after close error. Switch to .update_idletasks ignores close event, hence initialization gets to complete without error. Do we want to do that? I think not. If one tries to edit gigabyte file, idle/tk will probably hang and one very well might want close event handled. We could instead wrap test.tag_config with try: except AttributeError. Original authors assumed this would never happen, but its occurrence seems like a rare but legitimate possibility that should be allowed for. After sleeping, I will try to reproduce on my fast machine using Windows copy command. 3k EditorWindow.py is colorized too fast. -- versions: +Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22614 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22616] Allow connecting AST nodes with corresponding source ranges
Edward K. Ream added the comment: I urge the Python development team to fix this and the related bugs given in the Post Script. The lack of an easy way of associating ast nodes with text ranges in the original sources is arguably the biggest hole in the Python api. These bugs have immediate, severe, practical consequences for any tool that attempts to regularize (pep 8) or beautify Python code. Consider the code for PythonTidy: http://lacusveris.com/PythonTidy/PythonTidy-1.23.python Every version has had bugs in this area arising from difficult workarounds to the hole in the API. The entire Comments class is a horror directly related to these issues. Consider Aivar's workaround to these bugs: https://bitbucket.org/plas/thonny/src/8cdaa41aca7a5cc0b31618b6f1631d360c488196/src/ast_utils.py?at=default See the docstring for def fix_ast_problems. This is an absurdly difficult solution to what should be a trivial problem. It's impossible to build reliable software using such heroic hacks. The additional bugs listed below further complicate a nightmarish task. In short, these bugs are *not* minor little nits. They are preventing the development of reliable source-code tools. Edward K.

Based on the issue 10769 discussion, it sounds like it would be worthwhile to go to python-ideas and advocate for the position that the ast parser should be enhanced for the kind of use cases you are talking about. It is possible a PEP would be required, but it is also fairly likely that one will not be.

[issue22618] urllib.parse.parse_qsl different results after urllib.parse.unquote
R. David Murray added the comment:
Isn't it obvious that you have to parse before you unquote? That's the purpose
of quoting, after all. I suppose that is one of those beginner mind things
that is obvious only because I'm an experienced programmer...and that there are
web servers that do it wrong.
The docs could definitely use some improvement, since they don't mention that
parse_qs automatically unquotes the values...it is implicit in the fact that
urlencode with doseq=true is the inverse, and it encodes them, but it should be
made explicit.
You also might want to take note of the 'keep_blank_values' attribute, which
could also use a doc improvement (it isn't obvious from the text what 'blank
values' are):
parse_qs('a=1b=2b=1a%3Donly_appears_after_unquote',
keep_blank_values=True)
{'a': ['1'], 'b': ['2', '1'], 'a=only_appears_after_unquote': ['']}

[issue22616] Allow connecting AST nodes with corresponding source ranges
R. David Murray added the comment: OK, reading the followon links just added to issue issue 10769, it seems clear you don't need to advocate for the idea of supporting external tools, there seems to be consensus agreement for that. So now it is down to specific proposals and patches.

[issue22618] urllib.parse.parse_qsl different results after urllib.parse.unquote
Alex Vaystikh added the comment: It is much clearer after your insight: - I wasn't aware that 'parse_qs' unquotes values. That's most helpful! - I had no idea what 'keep_blank_values' were before your example, but now it couldn't be more obvious. I know that adding that example to docs would've helped me a lot! Maybe others?

[issue6478] time.tzset does not reset _strptime's locale time cache
R. David Murray added the comment: Berker: the patch doesn't apply cleanly any more. Also, about the test_bad_timezone modification...what about the previous check that the tzname wasn't in UTC/GMT? Isn't that still needed? Or perhaps better yet, an additional @run_with_tz decorator?

Serhiy Storchaka added the comment: The code you *add in this patch* uses os.popen, why not use subprocess instead? Added code is just modified copy of existing code. Furthermore, the code catches OSError when calling popen(), but popen() doesn't raise an exception. It can raise an exception in rare cases. The manual of pipe mentions this. The code of posix_popen() contains error handling. FYI os.popen() now calls subprocess... Not in 2.7. It's safer to use the subprocess module instead of using a shell (see the recent Shellshock story) to change the environment variables and to redirect stderr. May be, but this is different issue, which is not related to this issue. If os.popen should be replaced with subprocess, it should be done even without applying the patch of this issue. Please open new issue. However the recent Shellshock story affects only users of platforms which use bash or zsh as system shell (are there any?). subprocess now has a convinient subprocess.DEVNULL.
