Error in checking

I would like to give some feedback about ...

From: https://py.checkio.org/mission/acceptable-password-ii/solve/

isacceptablepassword("muchlonger5")

Has some error. When running my code in IDE, all works. I even tried using:

if password == "muchlonger5":
    return True

it still returns False...
