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

All three modify a list but differ in usage:

• list.remove(value) removes the first occurrence of the specified value. It raises ValueError if the value is not found.
• list.pop(index) removes and returns the element at the given index. If no index is provided, it removes the last element. It raises IndexError for an invalid index.
• del list[index] deletes the element at the specified index but does not return it. It can also delete slices (del list[start:end]). It raises IndexError for an invalid index.

Use remove when you know the value, pop when you need the removed element, and del for quick deletion without return or for slice deletion.
