我正在尝试重命名目录中的所有文件，对每个文件进行多次更改，以使文件名对互联网友好。它适用于一些替换，然后它说找不到文件。我虽然如果我放慢它的速度time.sleep()会起作用，但这似乎没有效果（除了变慢）。在某些情况下，我可以多次运行脚本并完成目标，但在某些情况下，它完成时没有错误，但没有进行更改。任何建议，将不胜感激。

import os, glob, time
path  = os.getcwd()
dirlist = glob.glob('*.pdf')
for filename in dirlist:
    os.rename(os.path.join(path, filename), os.path.join(path, filename.replace(' ', '_')))
    os.rename(os.path.join(path, filename), os.path.join(path, filename.lower().encode('utf8')))
    os.rename(os.path.join(path, filename), os.path.join(path, filename.replace(' (', '-')))
    os.rename(os.path.join(path, filename), os.path.join(path, filename.replace(')', '')))
    os.rename(os.path.join(path, filename), os.path.join(path, filename.replace(',', '')))
    os.rename(os.path.join(path, filename), os.path.join(path, filename.replace('_-_', '-')))

filename.replace()返回一个新字符串 - 它不会以任何方式更改文件名。所以文件名在重命名文件后会过时，并在下次使用时导致文件未找到错误。

尝试这样的事情：

import os, glob, time

def new_filename(filename):
    return filename.replace(' ', '_').lower().encode('utf8').replace(' (', '-') \
                   .replace(')', '').replace(',', '').replace('_-_', '-')

path  = os.getcwd()
dirlist = glob.glob('*.pdf')
for filename in dirlist:
    os.rename(os.path.join(path, filename), os.path.join(path, new_filename(filename)))
