Ah, my indents got removed from the above comment. You can prolly figure it out. It removes directories from variable all into variable dirs. Then adds the files left in variable all to the end of variable dirs.

If you have a directory with 100,000 listings, you might want to write a more efficient code function. Here’s a whack at it.
import os def custom_listdir(path): """ Returns the content of a directory by showing directories first and then files by ordering the names alphabetically """ all = sorted(os.listdir(path)); dirs = [] for i in xrange(len(all)-1, -1, -1): if os.path.isdir(path + os.path.sep + all[i]): dirs.append(all.pop(i)) dirs.extend(all)

Very nice, also if you use numpy you can also do something like this, using array’s built in argsort method

import numpy

dirs=array(os.listdir(‘./’))
dirs=dirs[dirs.argsort()]

Cool!

But to use you have to add an s in the return statement… (return dirs)
