Welcome! You may want to join the dedicated beginners forum

collaboratively teach foundational Python concepts.

That's right. The ‘totaltime’ name refers to a function. To ask whether
an integer object is less than a function object is not a meaningful
comparison.

If you want to *call* the function, use the “call this function”
syntax::

    totaltime()

That will evaluate to the return value when you call it, so use the
return value::

    if totaltime() < 10:
        # …
