💡 Model Answer
In Python, you can add values to a list using the append() method, the extend() method, or by concatenation. For example:
my_list = []
my_list.append(1) # adds a single element
my_list.extend([2, 3]) # adds multiple elements
my_list += [4] # another way to extend
print(my_list) # [1, 2, 3, 4]
append() runs in amortized O(1) time, while extend() and concatenation run in O(k) where k is the number of elements added.
