Example 1: Use of List append() Method

# Python program to demonstrate
# an example of list.append() method

# list
cities = ["New Delhi", "Mumbai"]

# print the list
print("cities are: ", cities)

# append two more cities
cities.append("Bangalore")
cities.append("Chennai")

# print the updated list
print("cities are:", cities)

cities are:  ['New Delhi', 'Mumbai']
cities are: ['New Delhi', 'Mumbai', 'Bangalore', 'Chennai']

Explanation

Initially there were two elements in the list ['New Delhi', 'Mumbai']
Then, we added two more city names (two more elements) - 1) 'Bangalore' and 2) 'Chennai', by using following python statements:

    cities.append('Bangalore');
    cities.append('Chennai');

'Bangalore' and the 'Chennai' will be added at the end of the list named cities.
Then, we printed the updated list; the output will be a new list with 4 elements ['New Delhi', 'Mumbai', 'Bangalore', 'Chennai'].

Example 2: Use of List append() Method

# Appending a list to the list

# list 1
cities = ["New Delhi", "Mumbai"]

# list to be added
newcities = ["Bangalore", "Chennai"]

# print the list

# append list
cities.append(newcities)

# print the updated list
print("Updated cities are:", cities)

Output

cities are:  ['New Delhi', 'Mumbai']
Updated cities are: ['New Delhi', 'Mumbai', ['Bangalore', 'Chennai']]
