Hello,

I am working on the Basta Fazoolin Project and I have the following error:

Traceback (most recent call last):
File “script.py”, line 34, in

I’m not sure exactly why but your code is rendering in a very odd way when I look at it. Assuming I’ve copied at least part of it right I’d suggest double-checking your indentation. To be part of the class any following statements should be indented (at least once). Once you drop the indentation you’re back in the global level script/module.

Couple of other things, it looks like there’s a return inside a loop which might exit earlier than you expect. Looks like a typo in the repr dunder method too, it’s __repr__.

Any reason why my list comprehension for question 16 didn’t work?

def available_menus(self, time):
     return [menu.name if menu.start_time <= time <= menu.end_time for menu in self.menus]

Also, does it make any difference if you keep all the class definitions at the top of the page as opposed to defining them as you go along the tasks?

I think the if stuff has to be at the end.

For example:

ls = [1, 2, 3, 4, 5, 6]
r = [num for num in ls if 3 <= num <= 5]
print(r)

Thank you

What about the classes? Do you happen to know the answer for that question too?

#6

I don’t think the order is particularly important; all the classes don’t have to be at the top …
as long as you define each thing before you use it.
