What is the difference between remove, pop, and del?

In Python lists, remove(value) deletes the first element that equals the specified value; it raises ValueError if the value is not found and returns None. pop(index) removes the element at the given index and returns that element; if no index is provided, it removes and returns the last item. del list[index] deletes the element at the specified index without returning it; it also supports slice deletion (e.g., del list[1:4]) and can delete the entire list (del list). pop is useful when you need the removed element, remove is handy when you know the value but not its position, and del is a statement that can delete items or slices and is often used for cleanup or to delete variables. All three raise IndexError or ValueError for invalid indices or values.
