Convenience functions for comparing Python system version

Project description

Convenience function for comparing Python system version


From the project root directory:

$ python install


Provides compare_python version so that you can check against the major, minor and micro version:

from versionutil import compare_python, PYTHON

# compare_python will return a boolean value against the current system version.
# PYTHON represents an instance of an object that is the current system version.

# It will check at the most significant value you signify. Default is equality check.
# True using 2.7.9:
PYTHON == '2'
PYTHON == '2.7'
PYTHON == '2.7.9'

# True using 3.4.4:
PYTHON == '3'
PYTHON == '3.4'
PYTHON == '3.4.4'

# False in 3.4.4:
PYTHON != '3.5'
PYTHON != '3.4.5'

# Works with ints and even floats:
PYTHON == 2.7

# Different comparisons exist, default comp='=='
PYTHON < 3.0
PYTHON > 2.6
PYTHON >= 2.7
PYTHON < 3.1
compare_python(3, '!=')
compare_python(3, '<')
compare_python(3.0, '<')
compare_python(2.6, '>')
compare_python(2.7, '>=')
compare_python(3.1, comp='<')

# To test against a custom system version (ignore sys.version_info):
compare_python(5.4, sysv=(5, 4, 5))
# or to create a PYTHON like object for 5.4.5:
from versionutil import PythonVersion
pv545 = PythonVersion(sysv=(5, 4, 5))
if pv545 == 5.4: # True...

# Useful for handling imports, where otherwise pyfuture and pasteurize might not have what you need.
if PYTHON < 3:
    from oldapi import OldAPI as API
elif PYTHON == 3.0 or PYTHON == 3.1:
    from newapi import OtherAPI as API
elif PYTHON >= 3.2:
    from newapi import NewAPI as API
