Python: using Modules

/ Published in: Python

Copy this code and paste it in your HTML

## Modules can be imported directly using the package or module name. Items in submodules must be accessed explicitly including the full package name.
 
>>> import os
>>> os.path.abspath(".")
'C:\\books\\python'
 
 
## Modules can be imported directly using the module name, but the namespace should be named something different. Items in submodules must be accessed explicitly including the full package name:
 
>>> import os as computer
>>> computer.path.abspath(".")
'C:\\books\\python'
 
 
## Modules can be imported using the module name within the package name. Items in submodules must be accessed explicitly including the full package name:
 
>>> import os.path
>>> os.path.abspath(".")
'C:\\books\\python'
 
 
## Modules can be imported by importing the modules specifically from the package. Items in submodules can be accessed implicitly without the package name:
 
>>> from os import path
>>> path.abspath(".")
'C:\\books\\python'
 
 
## Note:
reload(module)
 
## This function that reloads a module. This can be extremely useful during development if you need to update a module and reload it without terminating your program. However, objects created before the module is reloaded are not updated, so you must be careful in handling those objects.
