It works for me.

And although you can't put leading spaces in file names using
Windows explorer, you don't have to use command line rename.

I modified your program to also put leading spaces back in.

It works fine also. See sample run at end of code.

import os
import os.path
import string

# dirs is actually files and folders, not just folders.
dirs =  os.listdir(os.getcwd())
path = os.getcwd()
print path

for d in dirs:
    # If folder name begins with whitespace.
    if d[0] in string.whitespace:
        print d
        try:
            new_path = os.path.join(path, d.strip())
            old_path = os.path.join(path, d)
            print new_path
            print old_path
            os.renames(old_path, new_path)
        except Exception, e:
            print e

    # If folder name ends with whitespace.
    elif d[-1] in string.whitespace:
        print d
        try:
            new_path = os.path.join(path, d.strip())
            old_path = os.path.join(path, d)
            print new_path
            print old_path
            os.renames(old_path, new_path)
        except Exception, e:
            print e

    # Folder name is OK, so put spaces back in.
    else:
        if d[0] in '123':
            try:
                new_path = os.path.join(path, ' '*int(d[0])+d)
