A Program to print some Python built-in functions documents, such as abs(), int(), raw_input()

Please write a program to print some Python built-in functions documents, such as abs(), int(), raw_input()

    And add document for your own function

Hints:

    The built-in document method is __doc__

Solution:

print abs.__doc__

print int.__doc__

print raw_input.__doc__

def square(num):

    '''Return the square value of the input number.

   

    The input number must be integer.

    '''

    return num ** 2

print square(2)

print square.__doc__
