python - 递归重命名文件扩展名

Question

我很难创建一个 python 脚本，该脚本将重命名文件夹中的文件扩展名并继续在子目录中这样做。这是我到目前为止的脚本；它只能重命名顶级目录中的文件:

#!/usr/bin/python
# Usage: python rename_file_extensions.py

import os
import sys

for filename in os.listdir ("C:\\Users\\username\\Desktop\\test\\"): # parse through file list in the folder "test"

    if filename.find(".jpg") > 0: # if an .jpg is found

            newfilename = filename.replace(".jpg","jpeg") # convert .jpg to jpeg

            os.rename(filename, newfilename) # rename the file

Answer 1

import os
import sys

directory = os.path.dirname(os.path.realpath(sys.argv[0])) #get the directory of your script
for subdir, dirs, files in os.walk(directory):
 for filename in files:
  if filename.find('.jpg') > 0:
   subdirectoryPath = os.path.relpath(subdir, directory) #get the path to your subdirectory
   filePath = os.path.join(subdirectoryPath, filename) #get the path to your file
   newFilePath = filePath.replace(".jpg",".jpeg") #create the new name
   os.rename(filePath, newFilePath) #rename your file
