"6/7 Hey You Never Know!" Issues


#1

def hotel_cost(nights):
return nights*140
def plane_ride_cost(city):
if city=="Charlotte":
return 183
elif city=="Tampa":
return 220
elif city=="Pittsburgh":
return 222
elif city=="Los Angeles":
return 475
def rental_car_cost(days):
total=days*40
if days>=7:
total=total-50
elif days>=3 and days<7:
total=total-20
return total
def trip_cost(days, city, spending_money):
rental_car_cost(days)+plane_ride_cost(city)+spending_money

I keep getting an error similar to this:

Oops, try again. trip_cost('Tampa', 6, 0) raised an error: unsupported operand type(s) for -: 'str' and 'int'

I also have all of the proper indentions.


#2

Hi here

def trip_cost(days, city, spending_money):
rental_car_cost(days)+plane_ride_cost(city)+spending_money

You missing

hotel_cost(days)

#3

such as this?

def trip_cost(nights,days,city):
nights+days+city+spending_money


#4

No like that

def trip_cost(days, city, spending_money):
    return  rental_car_cost(days)+plane_ride_cost(city)+ hotel_cost(days) + spending_money

#5

Oh, I see. I wasn't aware I forgot to add in a 'return'.

thank you!


#6

now it's saying

Oops, try again. trip_cost('Los Angeles', 7, 0) raised an error: global name 'nights' is not defined

def hotel_cost(nights):
return nights*140
def plane_ride_cost(city):
if city=="Charlotte":
return 183
elif city=="Tampa":
return 220
elif city=="Pittsburgh":
return 222
elif city=="Los Angeles":
return 475
def rental_car_cost(days):
total=days*40
if days>=7:
total=total-50
elif days>=3 and days<7:
total=total-20
return total
def trip_cost(city,days,spending_money):
return hotel_cost(nights)+plane_ride_cost(city)+rental_car_cost(days)+spending_money


#7

Here inside hotel_cost(here) you should put days like that

hotel_cost(days)

#8

Héy Men,
this your code for solve this step:
================================
def hotel_cost(nights):
return 140 * nights
def plane_ride_cost(city):
if city == "Charlotte":
return 183
elif city == "Tampa":
return 220
elif city == "Pittsburgh":
return 222
elif city == "Los Angeles":
return 475
else:
return False
def rental_car_cost(days):
amount = 40 * days
if days >= 7:
amount -= 50
elif days >= 3:
amount -= 20
return amount
print rental_car_cost
def trip_cost(city, days, spending_money):
return rental_car_cost(days) + hotel_cost(days) + plane_ride_cost(city) + spending_money
================================

Hi why you have this part?

def cube(n):

And in which lesson are you?


#11

Hi there :slight_smile:

This is how the code is suppose to be for trip cost:

for trip_cost(city,days,spending_money): #Have 3 arguments

return spending_money + hotel_cost(days)+ plane_ride_cost(city)+ rental_car_cost(days)

include spending money , hotel cost, plane ride cost and rental car cost in the body of the function

print trip_cost("Tampa",7,67)
**test as a sample run (use in this format to avoid concatenation error) .Its format is (city,day,spending money). The string (city) must always be first to avoid concatenation error :slightsmile:_**

Hope this helps :slight_smile: :slight_smile: !

Hey, I'm not here to talk about coding i just want to ask you guys a pair a questions, pls:

  1. Do you how to delete a post? plz tell me.

  2. Have you guys seen my post? it's called "HEY, YOU NEVER KNOW! [project]" :confused::neutral_face:


#13

Thanks a bunch guys!
:grin::grin:


#14

Hey guys, can you PLEASE PLEASE help me. This is what I have:

def hotel_cost(nights):
return 140.0 * nights

def plane_ride_cost(city):
if city == "Charlotte":
return 183
elif city == "Tampa":
return 220
elif city == "Pittsburgh":
return 222
elif city == "Los Angeles":
return 475

def rental_car_cost(days):
cost = days * 40
if days >= 7:
cost -= 50
elif days >= 3:
cost -= 20
return cost

def trip_cost(city, days):
return hotel_cost(days) + plane_ride_cost(city) + rental_car_cost(days)

It keeps telling me: "Oops, try again. trip_cost should take exactly 3 arguments!"


#15

hey guys, i dont know why but i keep receiving and error saying trip_cost() takes exactly 3 arguments (2 given). i have 3????

def hotel_cost(night):
return 140*night

def plane_ride_cost(city):
if city == 'Charlotte':
return 183
elif city == 'Tampa':
return 220
elif city == 'Pittsburgh':
return 222
elif city == 'Los Angeles':
return 475
else:
return 0

def rental_car_cost(days):
if days >= 7:
car_rent = (days*40) - 50
return car_rent
elif days >=3 and days <= 7:
car_rent = (days*40) - 20
return car_rent
else:
car_rent = days*40
return car_rent

def trip_cost(city,days,spending_money):
return rental_car_cost(days) + plane_ride_cost(city) + hotel_cost(days) + spending_money

print trip_cost('Tampa', 4)


#16

I'm getting this message : Oops, try again. trip_cost('Tampa', 2, 0) raised an error: 'int' object is not callable

Which is perplexing because I haven't seen this error in the previous lessons.

For reference, my code looks like this:

def hotel_costs(days) :
return 140*nights
def plane_ride_cost(city) :
if city == "Charlotte":
return 183
if city == "Tampa":
return 220
if city == "Pittsburgh":
return 222
if city == "Los Angeles":
return 475
def rental_car_cost(days) :
cost = 40*days
if days>=7:
cost-=50
elif days>= 3:
cost-=20
return cost

def trip_cost(city,days,spending_money):
return rental_car_cost(days)+hotel_cost(days)+plane_ride_cost(city)+spending_money(days)


#17

def hotel_cost(nights):

return 140*nights

def plane_ride_cost(city):

if city == 'Charlotte':
    return 183
elif city == 'Tampa':
    return 220
elif city == 'Pittsburgh':
    return 222
elif city == 'Los Angeles':
    return 475

def rental_car_cost(days):

cost=days*40

if days>=7:
    return cost-50
elif days>=3 and days <7:
    return cost-20
else:
    return cost

def trip_cost(city,days,spending_money):
return rental_car_cost(days) + hotel_cost(days) + plane_ride_cost(city)+spending_money


#18

This still doesn't work, it's saying Oops, try again. Oops! Did you accidentally delete the trip_cost function?


#20

def hotel_cost(nights):
hotbill = 140 * nights
return hotbill

def plane_ride_cost(city):
if city =='Charlotte':
return 183
elif city == 'Tampa':
return 220
elif city == 'Pittsburgh':
return 222
elif city == "Los Angeles":
return 475
def rental_car_cost(days):
cost = days * 40
if days >= 7:
cost -= 50
return cost
elif days >= 3:
cost -=20
return cost
else:
cost +=0
return cost
def spending_money(cash):
if cash > float(0):
return cash
else:
cash=float(0)
return cash
