Python error: FileNotFoundError: [Errno 2] No such file or directory

Question

I am trying to open the file from folder and read it but it\'s not locating it. I am using Python3

Here is my code:

import os
import glob

prefix_path          


        

Answer 1

You are using relative path where you should be using an absolute one. It's a good idea to use os.path to work with file paths. Easy fix for your code is:

prefix = os.path.abspath(prefix_path) 
file_list = [os.path.join(prefix, f) for f in os.listdir(prefix) if f.endswith('.txt')]

Note that there are some other issues with your code:

1. In python you can do for thing in things. You did for thing in range(len(things)) it's much less readable and unnecessary.

2. You should use context managers when you open a file. Read more here.
