How to list files with python with their alphanumeric value?

Question

I have a directory with these .txt files:

1.txt
2.txt
3.txt
...
100.txt
138.txt
...
100.txt
1923.txt

If I list the directory with python (usign glob or os.listdir()), it produces such result:

adaptedUsers = sorted(glob.glob(dirName + '*.txt'))

1.txt
10.txt
1000.txt
..
2.txt
..

However I want to list the files in sorted with their numeric value as in windows directory files listing. How can I do this without renaming the files?

Answer 1

yes. Use split and sort with a key.

def natural_sort(x):
   radix = x.split(".")[0]
   return int(radix) if radix.isdigit() else 0

sorted_list = sorted(os.listdir("."),key = natural_sort)

handles the case where there are non-numeric files in the directory.
