How can I extend a list in Python?
An example of an AI chatbot conversation about extending lists in Python.
How can I extend a list in Python?
You can use the extend() method to add elements from another iterable to your list. For example, my_list.extend([4, 5]).
What if I want to add multiple lists together?
You can use the += operator or the extend() method. For example, list1 += list2 will combine both lists.
Can I use the append() method instead?
No, append() adds a single element to the end of the list. Use extend() for adding multiple elements.
Are there any performance differences between extend() and +=?
Both are efficient, but extend() is more explicit about your intention to add multiple elements.
