Answer 1

To modify a text file inplace, you could use fileinput module:

#!/usr/bin/env python3
import fileinput

username = input('Enter username: ').strip()
with fileinput.FileInput("users.txt", inplace=True, backup='.bak') as file:
    for line in file:
        if line.startswith(username + "/"):            
            line = line.replace("/False", "/True") 
        print(line, end='')
