Question

I\'m new to Python and programming in general. I am taking a module at university which requires me to write some fairly basic programs in Python. However, I got this feedback o

Answer 1

There's thing called Docstring in python (and here're some conventions on how to write python code in general - PEP 8) escaped by either triple single quote ''' or triple double quote """ well suited for multiline comments:

'''
    File name: test.py
    Author: Peter Test
    Date created: 4/20/2013
    Date last modified: 4/25/2013
    Python Version: 2.7
'''

You also may used special variables later (when programming a module) that are dedicated to contain info as:

__author__ = "Rob Knight, Gavin Huttley, and Peter Maxwell"
__copyright__ = "Copyright 2007, The Cogent Project"
__credits__ = ["Rob Knight", "Peter Maxwell", "Gavin Huttley",
                    "Matthew Wakefield"]
__license__ = "GPL"
__version__ = "1.0.1"
__maintainer__ = "Rob Knight"
__email__ = "rob@spot.colorado.edu"
__status__ = "Production"
