Python Os.path.dirname Returns Unexpected Path When Changing Directory

Currently I do not understand, why pythons os.path.dirname behave like it does. Let's assume I have the following script: # Not part of the script, just for the current sample __fi

Solution 1:

Look into os.path.normpath

Normalize a pathname by collapsing redundant separators and up-level references so that A//B, A/B/, A/./B and A/foo/../B all become A/B. This string manipulation may change the meaning of a path that contains symbolic links. On Windows, it converts forward slashes to backward slashes.

The reason os.path.dirname works the way it does is because it's not very smart - it even work for URLs!

os.path.dirname("http://www.google.com/test")  # outputs http://www.google.com

It simply chops off anything after the last slash. It doesn't look at anything before the last slash, so it doesn't care if you have /../ in there somewhere.

Solution 2:

os.path.normpath() will return a normalized path, with all references to the current or parent directory removed or replaced appropriately.
