Create new folders using python

Question

I am trying to create folders using the following code. Something is not correct and leads to error:

"TypeError: 'str' object is not callable"

import os, sys

a= [4,3,2,1]
print len(a)
for idx in range (len(a)):

    newpath = r'E:\test\tool\folder_%s'(idx) 
    if not os.path.exists(newpath): os.makedirs(newpath)

Using os.makedirs I can create folders. However, I am not able to suffix those folders in a loop. Any ideas can be helpful. Thanks.

Sorry. That was too dumb of me. Please disregard this question. The orignal code is big and I seem to have overlooked that % accidently got deleted — user741592

import os, sys

a= [4,3,2,1]
print len(a)
for idx in range (len(a)):

    newpath = ((r'E:\test\tool\folder_%s') % (idx)) 
    if not os.path.exists(newpath): os.makedirs(newpath)

Try that, if it helps, accept the answer, if not leave a comment and I'll delete it.

I think the preferred way to make strings is to use the format method.

newpath = 'E:\test\tool\folder_{0}'.format(idx)

This code will create the folder with name client_1001-test to client_1500-test

import os, sys

for i in range(1001, 1500):
    newpath = ((r'/tmp/fileSet/client_%s-test') % (i)) 
    if not os.path.exists(newpath): os.makedirs(newpath)
