Open file type file in python

Question

I have little mail filessaved without any extension:

how to open them?

Answer 1

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

Thus, the file will always be closed.

Answer 2

To add an answer to @ math2001, you can do something like this:

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

Another way:

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)
