14. Modules¶

14.1 Overview¶

import sys
def main():
    v = sys.version_info
    print('Python version {}.{}.{}'.format(*v))

sys module provides version_info, platform (linux or mac/darwin), etc
os module provides name, getenv('PATH'), getcwd(), urandom(25) (byte object), etc
random provides randint(1, 1000), shuffle, etc
datetime provides datetime.now(), datetime.now.year(), datetime.now.day(), etc.
Important to know what modules exist so you can use them and not reinvent the wheel.
