In the example, we insert three new elements to a list. vals.insert(0, -1) We insert the -1 value at the beginning of the list. Remember that Python lists are indexed from 0. vals.insert(len(vals), 5) We insert the 5 value at the end of the list. This is equivalent to ...
Adding items in a list typically refers to appending new elements to the end of the list, inserting them at specific positions within the list, or extending the list with elements from another iterable object.We can add list items in Python using various methods such as append(), extend() ...
