python open all files ending with .txt in a relative folder

This way you can get a list of files in a path as a list

You can also filter for file types

import glob

for file in glob.iglob('../../input_files/**.**',recursive=True):
    print(file)

Here you can specify the file type : **.**

for example: **.txt

Output:

../../input_files/name.type

You can use listdir from the os library, and filter out only the files which has txt as the ending

from os import listdir
txts = [x for x in listdir() if x[-3:] == 'txt']

Then you can iterate over the lists and do your work on each file.

Don't worry about the Absolute path, below line gives you the Absolute path where your script runs.

import os

script_dir = os.path.dirname(__file__)  # <-- absolute dir to the script is in

Now you can merge your relative path to the Absolute path

rel_path = 'relative_path_to_the_txt_dir'
os.path.join(script_dir, rel_path)  # <-- absolute dir to the txt is in

If you print the above line you'll see the exact path your txt files located on.

Here is what you are looking for:-

import glob
import os

script_dir = os.path.dirname(__file__)  # <-- absolute dir to the script is in
rel_path = 'relative_path_to_the_txt_dir'
txt_dir = os.path.join(script_dir, rel_path)  # <-- absolute dir to the txt is in

for filename in glob.glob(os.path.join(txt_dir, '*.txt')):  # filter txt files only
   with open(os.path.join(os.getcwd(), filename), 'r') as file:  # open in read-only mode
      # do your stuff

Here are few links that you can understand what I did:-

1. os.path.dirname(path)
2. os.path.join(path, *paths)
3. glob.glob(pathname, *, recursive=False)
