Python3-sys&shutil module Real-combat analysis

1.sys Module

Import SYS Print (sys.version)  # Get Python parser version information Print # get the program itself path Print (Sys.path)  # returns the search path for the module, initializing the value using the PYTHONPATH environment variable Print # returns the name of the operating platform

2.shutil advanced files, folders, compression package processing module
