Import and from import in Python

Python Path Introduction

Import the appropriate modules in Python using Import or From...import.

Module is actually a collection of functions and classes of files, it can achieve some of the corresponding functions, when we need to use these functions, the corresponding modules directly into our program, which is similar to the C language include header file, In Python we import the modules we need with imports.

Import Sys

Print (' ================python import mode========================== ');

Print (' The command line arguments is: ')

For I in SYS.ARGV:

Print (i)

Print (' \ n ' The Python path ', Sys.path)

From sys import Argv,path # import specific members

Print (' ================python from import=================================== ')

Print (' path: ', path) # because the path member has already been imported, there is no need to add sys.path when referencing it here

If you want to use all the SYS modules using the name, you can do this:

From SYS import *

Print (' path: ', path)
