开放式文件的文件在python

Question

我有几个mail files保存没有任何扩展：

如何打开它们？

Answer 1

with open('1', 'r') as fp: 
    content = fp.read() 

这样，文件将始终关闭。

Answer 2

要添加到@ math2001的答案，你可以做这样的事情：

numOfFiles = #int 
data = [] 

for files in range(1, numOfFiles+1): 
    with open(str(files), 'r') as f: 
     // do whatever data processing you need to do 
     fileData = f.read() 
     data.append(fileData) 

Answer 3

还有一种方法：

import os 
import glob 
files = filter(os.path.isfile, glob.glob("./[0-9]*")) 
for name in files: 
    with open(name) as fh: 
     contents = fh.read() 
     # do something with contents (parse email format)
