Python Bulk Blank folder creation

Question

i am trying to create bulk folders based on simple text file. os.makedir helps to create new folder but i am not sure how to incorporate with newpath variable along with folder list. following is what i am trying with. I understand that code has syntax error. So need some help to correct/enhance the code.

import os.path  
newpath = r'C:\Program Files\test\'  
with open('folders.txt') as f:  
    for line in f:  
        ff = os.makedirs(newpath,line.strip())  
        ff.close()

Use os.path.join to join path components.

import os.path  
newpath = r'C:\Program Files\test\'  
with open('folders.txt') as f:  
    for line in f:  
        os.makedirs(os.path.join(newpath, line.strip()))

Perhaps something like this?

import os, sys
newpath = 'C:\Program Files\test'
with open(open('folders.txt') as f:
  for line in f:
    newdir = os.path.join(newpath, line.strip())
    try:
      os.makedirs(newdir)
    except OSError:  # if makedirs() failed
      sys.stderr.write("ERR: Could not create %s\n" % newdir)
      pass  # continue with next line

Notes:

Use os.path.join() to combine a paths. This will automatically use separators that are suitable for your OS.
os.makedirs() does not return anything
os.makedirs() will raise an OSError exception if the directory already exists or cannot be created.

if i am not using '\\' i am getting SyntaxError ' EOL while scanning string literal' wondering if there is any tweak so i can use path with '\'. – user1582596 Aug 29 '12 at 11:04

See this question: http://stackoverflow.com/questions/2870730/python-raw-strings-and-trailing-backslash. For a quick solution, just skip the last slash (`r'C:\Program Files\test'`). `os.path.join()` will still do the right thing. Answer updated. – Shawn Chin Aug 29 '12 at 11:09
