Question

what's wrong with this python code ?
]
def rental_car_cost (days):
car_cost == days *40
return car_cost
if days >= 7:
return car_cost - 50
elif days >= 3 and days <7:
return car_cost - 20
else:
return False

def trip_cost (city, days):
total ammount = rental_car_cost+ hotel_cost+ plane_ride_cost

Answer 1

what errors/exceptions do you get?

Answer 2

probably you never use the if statement because you have the return statement just before it. let me know if it is that

Answer 3

I would concur with @MicroBot , the errors you are getting would be helpful and with your first return statement you are breaking out of your routine.

Answer 4

thanks for the answer :)

Answer 5

Your first, and probably most serious problem is: car_cost == days *40

== is a comparison operator. = is an assignment operator.

Then you can get into your discounts not being applied. BTW, in the elif statement, you don't need to check if days >= 7. It was checked in the if part of that structure.

Answer 6

totaly missed that...agree with @rsmith6559
it is very important to understand the difference between a comparison operator (==) and an assignment operator (=).
