How to add elements to a list in Python

Question

I want to declare a list in Python. After that, I would like to perform some list operations on it. How to do it?

Answer 1

To initialize an empty list do this:

new_list = []

or

new_list = list()

To add elements to the list, use append

new_list.append(12)

To extend the list to include the elements from another list use extend

new_list.extend([1,2,3,4])
new_list 
[12,1,2,3,4]

To remove an element from a list use remove

new_list.remove(2)
