将下载的文件改名。如 “141_你好.mp3” 改成 "141.mp3"

import os
import sys

if __name__ == "__main__":

    root = os.getcwd()

    for parent, dirs, fs in os.walk(root):

        for f in fs:
            if f.endswith(".mp3"):
                idx = f.find(".mp3")
                if (f.find("_") != -1):
                    idx = f.find("_")
                prefix = f[0:idx]
                ne = str(int(prefix)) + ".mp3"
                print("old={}, ne={}".format(f, ne))

                oldPath = os.path.sep.join((parent, f))
                newPath = os.path.sep.join((parent, ne))
                try:
                    os.rename(oldPath, newPath)
                except Exception as e:
                    print("error {}".format(e))
                else:
                    pass
