list.extend()
list.extend() is a Python method in the List Methods category. Extends the list by appending all items from the iterable. The syntax is list.extend(iterable). Parameters: iterable — items to add. Returns: None. A typical example: lst = [1, 2]
lst.extend([3, 4])
# lst = [1, 2, 3, 4]. A close sibling is list.append(), which appends an item to the end of the list. Modifies the list in place. A close sibling is list.insert(), which inserts an item at a given position. The first argument is the index. A close sibling is list.remove(), which removes the first occurrence of x from the list. Raises ValueError if not found. A close sibling is list.pop(), which removes and returns the item at the given position (last by default).
