Appending new items in a list using while loop

In this blog, we will create a list of 3 elements then use while loop to append new elements in a list. If user input ‘q’ then the while will be terminated and at the last display elements in the list

Create a list with three values. In below statement, we have created city list with 3 elements inside it

city = ['Paris','London','Mumbai']

Now use while loop to append or add new elements at the end. We will ask user to input city name and append that city in to the list. When user presses ‘q’ key, while loop will terminate

while city:
    new_city = input('Enter a city name: ')
    if new_city == 'q': break
    city.append(new_city)

Output

Enter a city name: Tokyo
Enter a city name: Beijin
Enter a city name: q
['Paris', 'London', 'Mumbai', 'Tokyo', 'Beijin']

Complete Code

city = ['Paris','London','Mumbai']
while city:
    new_city = input('Enter a city name: ')
    if new_city == 'q': break
    city.append(new_city)
print(city)
