If i put user == 'Q' only in the if block !! then it loops and works but if i write user == 'Q' or 'q' then it fails why??

#take.txt already exist in the same folder !! with open('take.txt', 'a') as ask: a = True while a: user = input('Why do you like programming?\n(Type Q to quit)\n') if user == 'Q' or 'q': break ask.write(user)

If user == "Q" or user =="q": Everybody comes across that bug on his coding journey 😉

I "q" evaluates True because "q" is a not empty string. If user == "Q" or "q": Is therefore always true. Some better opportunities might be If user.lowercase() =="q"# oops was it lowercase? Or If user in["Q","q"]: Just as u want
