working with File System in Python

Main libraries:

• import os (os docs)
• import pathlib (pathlib docs)

Setup

• For pathlib operations of file system, Path("the/path/string.txt")
• For pathlib operations of file path use PurePath("the/path/string.txt")

R/W on known paths

Check if stuff even exists

• os.path.exists(file_path_os) (check if path exists)
• os.path.isfile(file_path_os) check if thing is a file (not dir)
• Path.exists()
  • Path.mkdir(parents=True)

Parsing

• os.path.split()
• path = pathlib.PurePath("path/goes/here.txt") Pathlib accessing individual components
  • PurePath.anchor (root baisically)
  • PurePath.name -> filename.txt
  • PurePath.suffix -> .txt
  • PurePath.stem -> filename without suffix
