Common List Operations

Explore how to manipulate Python lists by learning to add, remove, slice, search, and sort elements. This lesson helps you work efficiently with lists as a fundamental data structure, enabling you to handle dynamic data and perform common operations confidently.

num_list.append(3)
print(num_list)
