I need to lock a file for writing in Python. It will be accessed from multiple Python processes at once. I have found some solutions online, but most fail for my purposes as they are often only Unix based or Windows based.
Alright, so I ended up going with the code I wrote here, on my website (also available on GitHub). I can use it in the following fashion:
from filelock import FileLock
# work with the file as it is now locked
