Question

I have strings in my python application that look this way:

test1/test2/foo/

Everytime I get such a string, I want to reduce it, beginning from the tail and reduced until the fist “/” is reached.

test1/test2/

More examples:

foo/foo/foo/foo/foo/  => foo/foo/foo/foo/
test/test/            => test/
how/to/implement/this => how/to/implement/

How can I implement this in python?

Thanks in advance!

 newString = oldString[:oldString[:-1].rfind('/')]
 # strip out trailing slash    ----^       ^---- find last remaining slash
