[bagratte]

useful for those who routinely use different versions of python on idle. as it ships, idle displays "python shell" on its title bar. it would be useful to have there the version displayed as well.

see http://bagratte.blogspot.it/2013/03/display-python-version-on-idle-title-bar_10.html

[merwok]

Sounds like a good idea to me. Would you like to propose a patch? The devguide contains information to do that.

Hint: sys.version is not meant to be parsed, there is sys.version_info for that (no regex needed! :)

[terryjreedy]

I agree. Sometimes when I have multiple IDLE windows open I have to scroll back to the top to make sure which one I am in. I suggest:
Python x.y Shell for shell window
I am not sure, for edit window: currently xxx.py -- <path>/xxx.py
I am not sure the redundancy is needed, but I do tended to look at the isolated file name. Maybe "xxx.py -- in <path>/" without filename at end.
Add 'Python x.y', 'Py x.y' 'x.y', beginning or end of line?

[bagratte]

...
class PyShell(OutputWindow):

    import platform
    version = platform.python_version() + " " + platform.architecture()[0]
    shell_title = "Python %s Shell" % version
...
(PyShell.py)

i'll take a look at the devguide and see if i can figure a patch out.

[bagratte]

or better still:

...
from platform import python_version, architecture
shell_title = "Python %s %s Shell" % (python_version(), architecture()[0])
...

[edmondburnett]

Suggesting a patch which addresses this enhancement. I did not include architecture() in the title bar but can add it as well if others think it is appropriate.

Import of platform.python_version is done at the top of PyShell.py rather than inside the class as per PEP-8.

[bagratte]

good. thank you.

i'm not sure about the architecture. i understand it's not crucial for most of the users. i would like to have it though.

[edmondburnett]

Updated patch to conform to PEP-3101

[ezio-melotti]

The 0 in "{0}" can be omitted, otherwise patch looks good to me. I agree that the architecture is not necessary.

[terryjreedy]

I have been planning to test and commit some version of this patch after PEP-434 is resolved, as I would like to backport it at least to 2.7 and 3.3. The only thing that could break is some esoteric application that looks at window title bars from outside and looks for an exact match rather than startswith('IDLE') or the equivalent.

[ezio-melotti]

I think it's safe to apply this patch to 2.7/3.2/3.3/3.4.

For a patch more complicated than this, the CA would now be required before applying a patch of yours.
