[issue14894] distutils.LooseVersion fails to compare number and a word

Sam Lai added the comment: I have a more realistic example of this bug. In the docstring for distutils.LooseVersion, it says '1.5.1' and '3.2.p10' are both valid version numbers. If instead of '3.2.p10', we use '1.5.p10', the following occurs - >>> v1 = LooseVersion('1.5.1') >>> v2 = LooseVers
