SyntaxError: can't assign to operator
Below your existing code, define a function called rental_car_cost with an argument called days.
Calculate the cost of renting the car:
Every day you rent the car costs $40.
if you rent the car for 7 or more days, you get $50 off your total.
Alternatively (elif), if you rent the car for 3 or more days, you get $20 off your total.
You cannot get both of the above discounts.
Return that cost.
before_discount_cost = 0 def rental_car_cost(days): days * 40 = before_discount_cost if days >= 7: return before_discount_cost - 50 elif days >= 3: return before_discount_cost - 20 else : return before_discount_cost
