重命名文件夹中的文件 - Python

Question

How can I rename files inside a folder without knowing their original name? For example I have a file.jpg and without knowing what it's called I want to call it test.jpg, this with all the files inside a folder.

Answer 1

Try this:

import os
import glob
# Getting all files in a folder (including hidden files)
files = os.listdir(os.path.expanduser("~/Downloads"))

# Getting all .jpg files in a directory
jpeg_files = glob.glob(os.path.expanduser("~/Downloads/*.jpeg"))

print(jpeg_files)
os.rename(jpeg_files[0], os.path.expanduser("~/Downloads/test.jpeg"))

If you want to rename all of the .jpeg files, then replace the last line with:

for file in jpeg_files:
    os.rename(file, os.path.expanduser("~/Downloads/test.jpeg"))

Right now I'm using os.expanduser() just so that it's easier for people to test
