There is one issue, however: a task cannot be added to a checklist if the name requested is already being used by another task in that checklist. In that case, this function must print a specific message and must return None Define addTask with 2 parameters Use def to define addTask with 2 parameters Use a return statement Within the definition of addTask with 2 parameters, use return _ in at least one place. Do not use any kind of loop Within the definition of addTask with 2 parameters, do not use any kind of loop.arrow_forwardTHIS IS FOR C++ ONLY Part 2b: Password Verification A secure password is critically important in today's world.
