Avoiding partially written files in Python

Question

What is the "safest" way to write files in Python? I've heard about atomic file writing but I am not sure of how to do it and how to handle it.

Answer 1

What you want is an atomic file replacement, so that there is never unfinished final file on the disk. There only exist complete new version or complete old version on the target location.

The method for Python is described here:
