A little script that recurses into the subdirectories of a specified folder and reports the numbers of filenames containing the specified file extension in each base-directory folder. I use it to find which of my Music library's artist folders contain the most mp3s and m4as. so I could focus on replacing those with oggs. Usage: $ countfiles ~/Mu…

#!/usr/bin/env python3
import os
from sys import argv

# Walk through folders recursively, list the full path and number of (extension) files found in each.

basefolder = os.path.expanduser(argv[1])
filetype = str(argv[2]).lower()
output = []

# New system:
for folder in os.listdir(basefolder):
    filecounter = 0
    for subf, childf, files in os.walk(os.path.join(basefolder,folder)):
        for filen in files:
            if filetype in filen.lower():
                filecounter += 1
    if filecounter:
        #print(folder, "contains {0} mp3s.".format(filecounter))
        output.append([filecounter, folder])

# As first list item is an integer, will be sorted by this. Largest last.
output.sort()

print("Count, Path")
for x in output[:]:
    newx = str(x[0]) + "\t" + x[1]
    output[output.index(x)] = newx
print("\r\n".join(output))
