Practice Makes Perfect?


I'm working on Practice Makes Perfect, and I thought I had a working code but I keep getting the error message "by_three(1) returned False instead of False"... What does that mean and how can I fix it? Pretty sure False and False are the same thing.


return "False"

should be

return False

without the quotes.

False is a boolean value.
"False" is a string.
The exercise requires you to return boolean values only, so you have to remove the quotes to make it a boolean value, rather than the string "False"
