In git revert -m, the -m alternative specifies the father or mother range. This is necessary for the reason that a merge commit has more than one dad or mum, and Git doesn't know routinely which guardian was the mainline, and which mum or dad was the branch you ought to un-merge.
Applying scandir() in lieu of listdir() can appreciably improve the general performance of code that also needs file type or file attribute info, simply because os.DirEntry objects expose this info If your operating technique gives it when scanning a directory.

If you need to Test that a file exists before you decide to try to go through it, and you may be deleting it and after that you might be using various threads or processes, or An additional here application is familiar with about that file and could delete it - you danger the prospect of a race situation if you Check out it exists, since you are then racing
