What is the difference between the pop and delete methods when working with lists in Python?

The pop method in Python removes an element from a list by index and returns it. If no index is specified, it removes the last element. This is convenient when you need to get the removed element.

Example:

lst = [10, 20, 30]
item = lst.pop(1)  # removes the element at index 1 (20) and returns it
print(item)  # 20
print(lst)   # [10, 30]

The del operator removes an element or slice from a list by index but does not return it. It is used for deletion without needing to get the value.

Example:

lst = [10, 20, 30]
del lst[1]  # removes the element at index 1
print(lst)  # [10, 30]

Summary:

• pop removes and returns the element
• del simply removes the element without returning

pop is useful when you need the removed element, del when you just want to delete.
