    In Python, you cannot append more than one element at a time using list.append() because it only adds a single object. However, there are several efficient ways to add multiple elements at once.

    Example using extend()

    fruits = ["apple", "banana"]
    fruits.extend(["cherry", "mango", "orange"])
    print(fruits)
    # Output: ['apple', 'banana', 'cherry', 'mango', 'orange']
    コピーしました。

    Here, extend() takes an iterable and adds each element individually to the list.

    Using extend() Best for adding multiple elements from any iterable (list, tuple, set, range).

    nums = [1, 2]
    nums.extend((3, 4, 5))
    print(nums) # [1, 2, 3, 4, 5]
    コピーしました。

    This modifies the list in place and is more efficient than looping with append().

    Using += Operator A shorthand for extend(), works with any iterable.

    letters = ["a", "b"]
    letters += ["c", "d"]
    print(letters) # ['a', 'b', 'c', 'd']
    コピーしました。

    Keeps the original list reference intact.

    Using List Concatenation (+) Creates a new list by merging two lists.

    a = [1, 2]
    a = a + [3, 4]
    print(a) # [1, 2, 3, 4]
    コピーしました。

    Note: This returns a new list instead of modifying in place.

    How to append a list in Python?

    Python provides a simple and efficient method called append () to accomplish this task. The syntax for the append () method is straightforward: Here, list_name refers to the name of the list to which the item will be appended, and item represents the element that you want to add to the list.
