OS module: Operating system interface

You should use the Import OS style instead of the From OS import *. This ensures that Os.open (), which varies with the operating system, does not overwrite the built-in function open () is useful for using the Dir () and help () functions built into large modules such as the OS.

For daily file and directory management tasks, the Shutil module provides an easy-to-use, high-level interface.

Glob module: Generate a list of files from the directory wildcard search

1 Import Glob,os 2 os.chdir ('Desktop')3 glob.glob ('*.desktop  ')4 ans: ['xxx.desktop']

Command-line arguments: command-line arguments are stored as a list of argv variables in the SYS module.

1 Import SYS 2 Print sys.argv

SYS also has the Stdin,stdout,stderr property, which can be used to display warnings and error messages even when STDOUT is redirected.

Sys.stderr.write (' warning .... ')

Most scripts are directed to terminate using Sys.exit ()

' Tea for too '. Replace ('too','both ')
