What is __doc__?The string documentation of an object (based on docstring)Prints the documentation of an objectCreates man file

doc is a special attribute in Python that retrieves the docstrings of Python objects. Docstrings are the string literals that appear right after the definition of a function, method, class, or module. They are used to explain what the object does and are used by the help() function in Python to display the documentation of the object.

Here's an example:

def add_numbers(a, b):
    """
    This function adds two numbers.
    :param a: The first number
    :param b: The second number
    :return: The sum of the two numbers
    """
    return a + b

print(add_numbers.__doc__)

When you run this code, it will print the docstring of the add_numbers function:

This function adds two numbers.
:param a: The first number
:param b: The second number
:return: The sum of the two numbers

So, doc does not create a man file, it simply retrieves the docstring of a Python object.
