Python Python Basics Functions and Looping Raising Exceptions

Number of people Wouldn't you want the if statement in the function to account for >= 2 people?

If there's no point in including 1 person (since you're splitting the check) why not just make the default values be 2 and higher? There would also be no point in having half of a person (1.5) and would relieve another potential error, correct?

If you account for >=2, what happens if you only have one person? If there is one person, don't split the check so ideally, you'd have something along the lines of:

if (people >= 1):
   split_check(check) #assuming you have function to split check amount/2
else:
   print(check) #or total dollar amount

Generating the exception when the number is <=1 does allow two or more already.

If you wanted to be sure that the given number has no fractional part, you could have an additional test:

if number_of_people != math.floor(number_of_people ):
   raise ValueError("You can only have whole numbers of people!")
