Answer 1

You can shift the lines in the for loop.

for file in os.listdir("/Users/coder/Desktop/Sample Folder"):
    if file.endswith(".txt"):

        with open(os.path.join("/Users/coder/Desktop/Sample Folder", file),"a+") as file:
            file.write("This file is a .txt file")

Answer 2

You can enter data like this,

import glob
import os
path = 'E:\Path'
for filename in glob.glob(os.path.join(path, '*.txt')):
   with open(os.path.join(os.getcwd(), filename), 'a') as f:
       f.write("Type the required information")
       

Change the path to the folder you are changing the text of
