How To Stop Traversing Current Root And Iterate To The Next One

I'm writing a simple function that walks through a directory tree looking for folders of a certain name. What I'm after is a match's parent path. E.g., for 'C:/a/b/c/MATCH' I want

Solution 1:

Trim dirnames to an empty list to prevent further traversing of directories below the current one:

defFindProjectSubfolders(masterPath, projectSubfolders):
    for currRoot, dirnames, filenames in os.walk(masterPath):
        # check if have a project subfolder
        foundMatch = Falsefor dirname in dirnames:
            for projectSubfolder in projectSubfolders:
                if (dirname == projectSubfolder):
                    foundMatch = True;
                    breakif (foundMatch == True):
            # what goes here to stop traversing "currRoot"# and iterate to the next one?
            dirnames[:] = []  # replace all indices in `dirnames` with the empty list

Note that the above code alters the list dirnames refers to with a slice assignment, it does not rebind dirnames to a new list.
