hardest week yet: some guidence please

Just add five to start. Don't slice something else. Add five to start. And that's assuming you are searching for 'user', so you need 5 characters to get past 'user '. If you are going to change the string you are searching for to 'Invalid user', you need to account for the extra length of that string. So you would need to add 13 to start. Note that if you were to slice 'Invalid user' by 13, you would get nothing. That's why you don't do that.

I know that is what I need to do I just cant figure out were it goes

start = line.find("invalid user")

I have tried it in many different places in the code
