How to read all .txt files from a directory

Question

I would like to read all the contents from all the text files in a directory. I have 4 text files in the "path" directory, and my codes are;

for filename in os.listdir(path):
    filepath = os.path.join(path, filename)
    with open(filepath, mode='r') as f:
        content = f.read()
        thelist = content.splitlines()
        f.close()
        print(filepath)
        print(content)
        print()

When I run the codes, I can only read the contents from only one text file.

I will be thankful that there are any advice or suggestions from you or that you know any other informative inquiries for this question in stackoverflow.

If you need to filter the files' name per suffix, i.e. file extension, you can either use the string method endswith or the glob module of the standard library https://docs.python.org/3/library/glob.html Here an example of code which save each file content as a string in a list.

import os

path = '.' # or your path

files_content = []

for filename in filter(lambda p: p.endswith("txt"), os.listdir(path)):
    filepath = os.path.join(path, filename)
    with open(filepath, mode='r') as f:
        files_content += [f.read()]

With the glob way here an example

import glob

for filename in glob.glob('*txt'):
    print(filename)
