Modules

A module is a file containing definition of functions, classes, variables, constants or any other Python object. Contents of this file can be made available to any other program. Python has the import keyword for this purpose.

Types

• Built in Modules (ex: os, datetime, operator etc)
• User Defined Modules

User Defined Modules

——mymodules.py——-

def myname(name):
    print('My Name', name)
    return

——mytestfile.py——

import mymodules
mymodules.myname('sunil')

Results: MyName sunil

Importing Modules:

• You can also use from mymodules import myname to import only myname function.
• You can also use from mymodules import * to import every function.
• You can assign an alias name to the imported module. from mymodules as x. When calling function use x.myname('Sunil').

Module Attributes

In Python, a module is an object of module class, and hence it is characterized by attributes.

Following are the module attributes −

• file returns the physical name of the module.
• package returns the package to which the module belongs.
• doc returns the docstring at the top of the module if any
• dict returns the entire scope of the module
• name returns the name of the module

ex:

import mymodules
print ("__file__ attribute:", mymodules.__file__)
print ("__doc__ attribute:", mymodules.__doc__)
print ("__name__ attribute:", mymodules.__name__)

Result:

__file__ attribute: /home/sunil/Desktop/Sunil/MyAutomation/Python/test.py
__doc__ attribute: None
__name__ attribute: test

Note: If you edit the .py file and save it, the function loaded in the memory won’t update. You need to reload it, using reload() function in imp module.
