A series of Python tips would be remiss without mentioning pathlib.Path, one of my favorite builtin modules. The Path object is intuitive and saves many headaches when dealing with files and folders and their cross-platform paths.
from pathlib import Path
# Directories
cwd = Path(".")
absolute = cwd.resolve()
my_dir = absolute / "folder" / "path"
assert my_dir.is_relative_to(absolute)
rel_dir = my_dir.relative_to(absolute)
my_dir.mkdir(parents=True, exist_ok=True)
# Directory contents
files = [f for f in cwd.iterdir() if f.is_file()]
dirs = [d for d in cwd.iterdir() if d.is_dir()]
recursive_py = sorted(my_dir.glob("**/*.py"))
# Files
myfile = my_dir / "myfile.ext"
assert myfile.stem == "myfile"
assert myfile.suffix == ".ext"
myfile.write_text("Available for hire.\n")
assert myfile.exists()
myfile.stat()
text = myfile.read_text()
myfile.unlink()
assert not myfile.exists()One of the many thing I like about the Path object is operator overloading that allows "dividing" path parts together, which makes it look like you are actually just writing the literal posix path. Actually, only today I learned of the methods Path.write_text, Path.read_text, and the corresponding bytes methods. This may be my new favorite feature of the pathlib module.
There is so much to this module and it's virtually all accessible with the one Path object. Check out the documentation!
