Assume the you have the following directory tree:
directory
- subdirectoryA
- image1.png
- image2.png
- ...
- subdirectoryB
- image1.png
- image2.png
- ...
You can count the number of files in each directory and print out the result.
Using os
import os
path = 'path/to/directory'
total = 0
for sub_dir in os.listdir(path):
target_dir = path + '/' + sub_dir
files = os.listdir(target_dir)
count = len(files)
total += count
print(f'{sub_dir}: {count}')
print(f'Total: {total}')
The result will look like this:
subdirectoryA: 100
subdirectoryB: 120
...
Total: 1000
Using pathlib
from pathlib import Path
data_root = Path('path/to/directory')
total = 0
for sub_dir in data_root.iterdir():
count = len(list(sub_dir.iterdir()))
total += count
print(f'{sub_dir.name}: {count}')
print(f'Total: {total}')
