Change the import so that you only import the sqrt function, like this:

Change the import so that you import everything from the math module, like this:

Taking a Vacation

"""
# Exercise 0 : Planning Your Trip
"""
First, write a function called hotel_cost that takes the
variable nights as input. The function should return how
much you have to pay if the hotel costs 140 dollars for
every night that you stay.
"""
def hotel_cost(nights):
return nights*140
# Exercise 1 : Getting There
"""
Write a function called plane_ride_cost that takes a
string, city, as input. The function should return a
different price depending on the location. Below are
the valid destinations and their corresponding round-trip prices.
"Paris": 183
"New York": 220
"Tokyo": 222
"Istanbul": 475
"""
def plane_ride_cost(city):
if city == "Paris":
return 183
elif city == "Tokyo":
return 222
elif city == "New York":
return 220
else:
return 475
# Exercise 2 : Transportation
"""
Write a function called rental_car_cost that takes days
as input and returns the cost for renting a car for said
number of days. The cost must abide by the following conditions:
Every day you rent the car is $40.
If you rent the car for 3 or more days, you get $20 off your total.
If you rent the car for 7 or more days, you get $50 off your total.
(This does not stack with the 20 dollars you get
for renting the car over 3 days.)
"""
def rental_car_cost(days):
raw_cost = days * 40
if days >= 3:
return raw_cost - 20
elif days >= 7:
return raw_cost - 50
# Exercise 3 : Pull it Together
"""
Now write a function called trip_cost that takes two inputs,
city and days. city should be the city that you are going to
visit and days should be the number of days that you are staying.
Have your function return the sum of the rental_car_cost,
hotel_cost, and plane_ride_cost functions with their respective inputs.
"""
# Exercise 4 : Expect the Unexpected
"""
Make it so that your trip_cost function takes a third parameter,
spending_money. Just modify the trip_cost function to do just as
it did before, except add the spending money to the total that it
returns.
"""
# Exercise 5 : Let's go!
"""
Now that you have it all together, print out the cost of a trip
to "New York" for 5 days with an extra 200 dollars of spending money.
