I looked though the os.path manual. I don't find a function that can test if a path is in a directory or its sub-directory (recursively). For example, /a/b/c/d is in /a its sub-directory (recursively). Could somebody let me know if such function is available somewhere?
Couldn't you just canonicalize the paths using os.path.abspath() and friends and then do subdirectory.startswith(parent_directory) [as strings]?
Beware of directories starting with the same letters. I'd canonicalize, split the strings on os.sep, and compare the resulting lists up to the shortest one.
Just to add one more comment. There are other corner cases where there is a symbolic link in the path. 'abspath()' may not be good for the corner cases.
