Common built-in libraries for Python

Standard library:

Import OS

OS.GETCWD ()//return current working path

Os.chdir ('/server/accesslogs ') # Change current working directory

The Dir () function is one of the most common and useful functions of python. It returns a list of all property names that contain the object to query

Import Shutil

Shutil.copyfile (' data.db ', ' archive.db ')//Copy files

Shutil.move ('/build/executables ', ' installdir ')//delete files

Returns a list of all matching file paths. It has only one parameter pathname, which defines the file path matching rule, which can be either an absolute or a relative path. Here's an example of using Glob.glob:
