There are two main ways to copy a list in Python:

# Method copy

The `list.copy` method can be leveraged to copy a list:

``` original_list = ['apples', 'bananas', 'pears', 'oranges']copy_list = original_list.copy()print(copy_list) ['apples', 'bananas', 'pears', 'oranges'] ```

# Slicing

We create a slice from the very start of `original_list` to the very end (i.e. copying the entire list)

``` original_list = ['apples', 'bananas', 'pears', 'oranges']copy_list = original_list[:]print(copy_list) ['apples', 'bananas', 'pears', 'oranges'] ```

# Incorrect way to copy

``` original_list = ['apples','bananas','pears','oranges']copy_list = original_list ```

The above syntax will lead to `copy_list` and `original_list` both pointing to the same list. Therefore updating `original_list` will also mean `copy_list` is updated automatically which is something we do not want.
