[Python] Why does it say that I have reached the max recursion depth? How can I fix it?

cities = ["Boston", "Las Vegas", "Porto Alegre", "Cape Town", "Berlin", "Okinawa", "Sydney"]
hotels = [255, 450, 150, 250, 650, 675, 850]
flights = [950, 3000, 4500, 2750, 2500, 3500, 10500]


def add_destination(city, hotel, flight):
global cities, flights, hotels
print("""Add your desired destination. Please include your hotel and flight cost,
as well as the name of your desired location and hotel.""")
new_place_city = input("Please type your new city: ")
new_place_hotel = int(input("Please type your new hotel's price per night: "))
new_place_flight = int(input("Please type the cost of your flight:"))
cities.append(new_place_city)
hotels.append(new_place_hotel)
flights.append(new_place_flight)

cost = [flights] + [hotels]

def calculate_total_cost(hotels, flights):
global city, hotel, flight, cost
f_cost = sum(flights)
h_cost = sum(hotels)
t_cost = sum({h_cost, f_cost})
result = calculate_total_cost(hotels, flights)




def display_budget_summary(cities, hotels, flights):
for i in range(len(cities)):
print(f"{cities}, ${hotels} ${flights}.")
result = calculate_total_cost(hotels, flights)
print(f"Your current budget/money spent is ${result}.")

while True:
print(f"""Currently, the cities you plan to visit during your vacation are {cities}."
Please choose an option to make any edits to your vacation.""")
print("1. Add a destination")
print("2. View budget summary")
print("3. Exit program")

option = int(input("Please choose an answer: "))

if option == 1:
add_destination(cities, hotels, flights)

elif option == 2:
display_budget_summary(cities, hotels, flights)

elif option == 3:
break

else:
print("Please choose a valid option.")


Provided above is my code. When I run this on Online Python, I receive the error message that I have reached the maximum recursion distance, and I am confused as to what I can due to fix this. From what I understand, most of the issues lie around the display function. Can anyone elaborate as to how I can fix this mistake?
