Python Python Basics Functions and Looping Raising Exceptions

I don't get why the code at 2:25 doesn't work

If the "raise" function raises a value error when the number of people is bellow or equal to 1, then shouldn't that error trigger the "except" function? Why is the amount_due = split_check(total_due, number_of_people) line even ran if it's under "else"? shouldn't the "else" function only be ran when there are no errors?

The split_check function and try block are separate. Except will execute only if there is an error in the try. At 2:25 there are no errors in the try (20 is converted to float and zero is converted to integer) so the else executes. That is when the error is raised from within the split_check function and the program ends.
