mainloop()

Whenever I run the program, I don't get an error message. However, when I type in what I have just set or set before as the password (in the txt file) or what is printed in the terminal, it sleeps the program like I got it wrong. I've posted this before and it was too long, so it's shortened now. This is just revision for my assessment.

CodePudding user response：

For example you can do:

File = open(‘file.txt’, ‘r’)
File_context = File.read()
File.close()

If ‘Word’ in File_context:
    Print(‘FOUND!’)

Tell me if it works!
