Solution 1:

Following this documentation, try this code:

is_64bits = sys.maxsize > 2**32

Note: this can return an incorrect result if 32bit Python is running on a 64bit operating system.

An alternative method. Definitely works on all platforms:

importstructis_64bit = struct.calcsize('P') * 8 == 64

As a note, this is part of its.py.
