What is the difference between append() and extend() methods in Python lists?

Question

Explain how to use both where to use bith

Answer 1

Both `append()` and `extend()` are methods used with Python lists, but they have difference

- The `append()` method is used to add a single element to the end of a list. For example:
```python
my_list = [1, 2, 3]
my_list.append(4)
# Now my_list is [1, 2, 3, 4]
```

- The `extend()` method is used to add multiple elements (from another iterable, like a list or tuple) to the end of a list. For example:
```python
my_list = [1, 2, 3]
my_list.extend([4, 5, 6])
# Now my_list is [1, 2, 3, 4, 5, 6]
```

Remember, `append()` adds a single element, while `extend()` adds multiple elements from an iterable.

Answer 2

Zahed Shaikh ,
list.append(element) - adds an element at the end of the list.
list.extend(list2) - adds each element of a specified list(list2)[CAN BE ANY TYPES, SUCH AS TUPLES OR SETS] at the end of the list.
Example:
x = [1,2,3]
x.append(4)
#x = [1,2,3,4]

mylist = [4,5,6]
y = [7,8,9]
mylist.extend(y)
#mylist = [4,5,6,7,8,9]
