get script directory name – Python [duplicate]

import os
os.path.basename(os.path.dirname(os.path.realpath(__file__)))

Broken down:

currentFile = __file__  # May be 'my_script', or './my_script' or
                        # '/home/user/test/my_script.py' depending on exactly how
                        # the script was run/loaded.
realPath = os.path.realpath(currentFile)  # /home/user/test/my_script.py
dirPath = os.path.dirname(realPath)  # /home/user/test
dirName = os.path.basename(dirPath) # test
