Write a python script to print the docstring(documentation string) of the input function.

Question

def input():
‘’‘this is doc string’’’
return None
print(input.doc)
help(input)

what is my mistake?

Answer 1

I'm not exactly sure what you're after.

If you want your function to return a value, you do not return None, but an actual value, which you can use later.

def input():
    return "Hello"

print(input())

Answer 2

Use .__doc__ to access the doc string of a function in python.

def func():
    """
    hello world
    """
print(func.__doc__)

Answer 3

‘’‘this is doc string’’’ to be changed to """this is doc string """

Note : use double quotes & not single quote.

print(input.doc)  to be changed to print input.__doc__

Please refer the documentation.
