推荐答案

这是一个疯狂的猜测，但我很确定这是你的问题，所以我会试一试.

This is kind of a wild guess, but I'm pretty sure that this is your problem, so I'll give it a try.

请注意，os.listdir 仅返回文件名列表；它不包括作为 os.listdir 参数的目录.即，您必须告诉 shutils.move 在哪里可以找到这些文件！此外，如果目标目录尚不存在，您可能必须创建它.试试这个:

Note that os.listdir returns a list of filenames only; it does not include the directory that was the parameter to os.listdir. I.e., you have to tell shutils.move where to find those files! Also, you might have to create the destination directory, if it does not yet exist. Try this:

import shutil, os
source = "/tmp/"
destination = "/tmp/newfolder/"
if not os.path.exists(destination):
    os.makedirs(destination)                 # only if it does not yet exist
for f in os.listdir(source):
    if f.endswith(".txt"):
        shutil.move(source + f, destination) # add source dir to filename
