How to Copy One List to Another in Python?

There are multiple ways to copy one list to another in Python. Here are a few commonly used methods:

1. Using the slice operator [:]:

list1 = [1, 2, 3, 4, 5]
list2 = list1[:]  # Copy list1 to list2

2. Using the copy() method:

list1 = [1, 2, 3, 4, 5]
list2 = list1.copy()  # Copy list1 to list2

or

list2 = list1.copy()

3. Using the list() function:

list1 = [1, 2, 3, 4, 5]
list2 = list(list1)  # Copy list1 to list2

4. Using the extend() method:

list1 = [1, 2, 3, 4, 5]
list2 = []
list2.extend(list1)  # Copy list1 to list2

5. Using list comprehension:

list1 = [1, 2, 3, 4, 5]
list2 = [x for x in list1]  # Copy list1 to list2

All of these methods create a new list (list2) that is a copy of the original list (list1). Modifying one list will not affect the other list. Choose the method that suits your specific use case and coding style.
