Comments and DOCSTRING

COMMENTS:

   

           * A hash sign (#) is the beginning of a comment.

           * Anything written after # in a line is ignored by interpreter.    

        Eg: percentage = (minute * 100) / 60 # calculating percentage of an hour 

            * Python does not have multiple-line commenting feature. 

     Eg : # This is a comment. 

            # This is a comment, too.

           # I said that already.

DOCSTRING:

       

           Docstring is short for documentation string. It is a string that occurs as the first statement in a module, function, class, or  

method definition. We must write what a function/class does in the docstring. Triple quotes are used while writing docstrings. 

Syntax:

Fuctionname__doc.__ 

Example :

def double(num):

"""Function to double the value"""

return 2*num

>>> print(double.__doc__)

Function to double the value
