Python List Pop

The pop() method of a list in Python removes the specified element from the list and returns it. If no index is specified, it removes and returns the last element of the list.

Here's an example:

my_list = [1, 2, 3, 4, 5]
popped_element = my_list.pop()
print(popped_element)  # Output: 5
print(my_list)  # Output: [1, 2, 3, 4]

In this example, the pop() method removes and returns the last element of the list (5).

If you want to remove an element at a specific position in the list, you can pass the index as an argument:

my_list = [1, 2, 3, 4, 5]
popped_element = my_list.pop(2)
print(popped_element)  # Output: 3
print(my_list)  # Output: [1, 2, 4, 5]

In this case, the pop() method removes and returns the element at index 2, which is 3.

Return value

The pop() method returns the removed element from the list. If the list is empty or no index is specified, it raises a ValueError.

Example with error handling

my_list = [1, 2, 3]
try:
popped_element = my_list.pop(5)  # Raises ValueError
except ValueError as e:
print(f"Error: {e}")
print(my_list)  # Output: [1, 2, 3]

In this example, we try to remove an element at index 5, which doesn't exist in the list. The pop() method raises a ValueError with a message indicating that the index is out of range.

Common use cases

The pop() method is useful when you need to:
