Python pathlib cast to str for subprocess
Python 3.6 made
pathlib
part of Python standard library.
When using Python
subprocess,
in general, do str(mypath) where type(mypath) is pathlib.Path.
Example:
#!/usr/bin/env python
from pathlib import Path
import subprocess
P = Path('~').expanduser()
O = subprocess.check_output(['dir', str(P)])
print(O)if you don’t cast pathlib.Path to str, you’ll get errors like:
TypeError: argument of type ‘WindowsPath’ is not iterable.
Notes
You should rarely if ever need shell=True.
On Windows in particular, give the full path to a non-system executable.
