python - IOError: [Errno 2] 没有这样的文件或目录

Question

我在尝试对文件夹中的许多文件进行迭代时遇到问题，这些文件存在，如果我从文件中打印文件，我可以看到它们的名称......我对编程很陌生，你能帮帮我吗？亲切的问候！

import os
for path, dirs, files in os.walk('FDF\FDF'):
    for file in files:
        print file
        fdf = open(file, "r")
IOError: [Errno 2] No such file or directory: 'FDF_20110612_140613_...........txt'

Answer 1

path在打开文件之前，您需要为每个文件名添加前缀。

请参阅os.walk.

import os
for path, dirs, files in os.walk('FDF\FDF'):
    for file in files:
        print file
        filepath = os.path.join(path, file)
        print filepath
        fdf = open(filepath, "r")

Answer 2

尝试这个：

import os

for path, dirs, files in os.walk('FDF\FDF'):
    for file in files:
        print file
        with open(os.path.join(path, file)) as fdf:
            # code goes here.
