This is a new serie of articles here at Python for beginners, that are supposed
to be a starting point for completely beginners of Python.
See it as a cheat sheet, reference, manual or whatever you want.
The purpose is to very short write down the basics of Python.
This page will describe how to use Modules in Python.
Python modules makes the programming a lot easier.
It’s basically a file that consist of already written code.
When Python imports a module, it first checks the module registry (sys.modules)
to see if the module is already imported.
If that’s the case, Python uses the existing module object as is.
There are different ways to import a module.
This is also why Python comes with battery included
Let's how the different ways to import a module
#access module, after this you can use sys.name to refer to things defined in module sys.
from sys import stdout
# access module without qualiying name.
This reads from the module "sys" import "stdout", so that we would be able to
refer "stdout"in our program.
from sys import *
# access all functions/classes in the sys module.
I like to use the import statement to ensure that all modules can be loaded
on the system.
The Import Error basically means that you cannot use this module, and that you
should look at the traceback to find out why.
print 'Import not installed'
Python Standard Library
Collection of of modules that are already on the system, there is no
need to install them.
Just import the modules you want to use.
