读取文件python时出错

Question

我正在尝试在目录中读取我的python文件.我收到了一个错误

Traceback (most recent call last):
  File "/home/akallararajappan/codes to handle unicode/read_directory.py", line 42, in <module>
    open_file( filename)
  File "/home/akallararajappan/codes to handle unicode/read_directory.py", line 31, in open_file
    data = open (fil_name, 'r').read()
IOError: [Errno 2] No such file or directory: 'createFile.py' 

这是我的代码:

import os
import codecs
def open_file(fil_name) :
    data = open (fil_name, 'r').read()
    print data 



for dirname, dirnames, filenames in os.walk('/home/akallararajappan/corpus'):
    print()
    #print(dirname + ":")
    for filename in filenames:
        open_file( filename)

这里有什么问题？

Answer 1

在文件名os.walk()做不有完整的路径; 他们总是相对的dirname.dirname在尝试打开文件之前先添加路径:

for dirname, dirnames, filenames in os.walk('/home/akallararajappan/corpus'):
    for filename in filenames:
        open_file(os.path.join(dirname, filename))
