Folders in folders

[jenost]

Hi!
Trying to create three different sub-folders named: "raw" "right" and "left" in one folder named from a txt file. I succeeded to make one sub-folder, "raw" in each.

import os
path = '/raw'
with open('regina.txt') as x:
    for line in x:
        line = line.strip()
        os.makedirs(line + path) 

Would appreciate tips on how to think/ solve this.
Thanks in advance!
