Python module

python modules are the basic way to organize your code

Python scripts are saved with a text file with the extension py, and a script can be run either alone or in another script. When a script is imported to run, it is called a module

Cat test.py

#!/usr/bin/python

#coding: Utf-8

From __future__ Import Division

def a (x, y):

Print X+y

def b (x, y):

Print X*y

Cat new.py

#!/usr/bin/python

Import Test

TEST.A (ON)

TEST.B (3,4)

Package

Python modules can be organized into packages by directory

The steps to create a package are:

--Create a folder named Package name

--Create a __init__.py file under this folder

--store script files, compiled extensions, and child packages under this folder as needed

mkdir/python/

touch/python/__init__.py

VI test.py

#!/usr/bin/python

Import Python.test

Print Python.test.a
