  • 0

So say I have a retrieved directory name, “LibX_00.03”, and I retrieve the version information of the directory with:

lib = "LibX_00.03"

version = lib[-5:]

After doing this I then want to compare this version number with others to assert the latest release of the library, the trouble with this being that is has to be in a numberic form for comparison and not a str.
Casting to int or float both do not work, as int will give a whole number, and float gives an innacurate conversion:

>>> float(version)
0.299999...

So how can I accurately preserve the version number while having it in a form where I make a comparison?

    >>> from distutils.version import StrictVersion
>>> StrictVersion('00.03') > StrictVersion('00.10')
False
>>> StrictVersion('00.03') > StrictVersion('00.02')
True

    Note this won’t work if you have '1.0b' as version string, for that use LooseVersion:

    >>> from distutils.version import LooseVersion
>>> LooseVersion('1.2b') > LooseVersion('0.1')
True
>>> LooseVersion('1.2b') > LooseVersion('1.2c')
False
