urse/project/kb/use.js

from this string i need to get

urse/project/kb/

Answer 1

Python has a dedicated module for dealing with file paths:

In [13]: os.path.dirname('urse/project/kb/use.js')
Out[13]: 'urse/project/kb'

Append a trailing os.sep as required (or, better yet, stick to using the os.path module for manipulating paths).
