FileNotFoundError，Python [英] FileNotFoundError, Python

问题描述

我正在尝试打开文件夹中的文件，但出现此错误:

I'm trying to open the files in my folder but it came out with this error:

FileNotFoundError: [Errno 2] No such file or directory: 'TRAIN_00000.eml'

我已经仔细检查了代码中写入的文件名和目录/路径，但问题仍然存在.

I had double check the file name and the directory/path written in the code but the problem still there.

代码如下:

import os

path = "C:\\Users\\...\\TRAINING"
listing = os.listdir(path)


for em in listing:
    file = open(em, 'rb')
    e_content = file.read()
    file.close()

print (e_content)

感谢任何帮助.:)

推荐答案

更改:

for em in listing:

到:

for em in listing:
    em = os.path.join(path, em) # this is what you need to add

这应该可以解决您的问题.os.listdir() 返回的是一个相对路径列表.如果您不调用 path 目录中的应用程序，则需要将它们设为绝对路径.否则，如您所见，它们不会被找到.

This should solve your problem. The return from os.listdir() is a list of relative paths. You need to make them absolute paths if you're not invoking the app in the path directory. Otherwise they are not found, as you've seen.
