Using Pathlib

Basics

from pathlib import Path

current = Path('.')
my_file = Path('/home/user/docs/file.txt')
absolute = Path(__file__).resolve()

Filesystem navigation

from pathlib import Path

# Go up one or more directories
parent = Path(__file__).resolve().parent
grandparent = Path(__file__).resolve().parents[1]
# Move into a subdirectory
subdir = parent / "my_folder"

Check path properties

p = Path("example.txt")

p.exists()      # Check if path exists
p.is_file()     # Is it a file?
p.is_dir()      # Is it a directory?

Other

# Read and write files
file = Path("example.txt")

file.write_text("Hello, pathlib!")
content = file.read_text()
print(content)

# iterate over a dir
for path in Path('.').iterdir():
    print(path)

# globbing
for py_file in Path('.').rglob('*.py'):
    print(py_file)
