Bug in Python Renaming Program…No such file or Directory (Fnmatch)

Question

I\'m trying to build a little renaming program to help save me time in the future. Basically it will go through directories I point it too and rename files if they meet cert

Answer 1

You'll need to include the full path to the filenames you are trying to rename:

import os
import fnmatch

directory = "/Users/Desktop/TESTME"
for file in os.listdir(directory):
    if fnmatch.fnmatch(file, 'MISC*'):
        path = os.path.join(directory, file)
        target = os.path.join(directory, file[4:12] + '-13-Misc.jpg'
        os.rename(path, target)

The os.path.join function intelligently joins path elements into a whole, using the correct directory separator for your platform.

Answer 2

The function os.listdir() only returns the file names of the files in the given directory, not their full paths. You can use os.path.join(directory, file_name) to reconstruct the full path of the file.

You could also do this in bash:

cd /Users/Desktop/TESTME/
for f in MISC*; do mv "$f" "${f:4:8}-13-Misc.jpg"; done
