What are Python lists and how do I use them?

Python lists are ordered collections of items that can hold a variety of data types. You can create a list using square brackets, like this: my_list = [1, 2, 3, 'apple', 'banana']. You can access elements by their index, modify them, and even nest lists.

How do I add items to a list?

You can add items to a list using the append() method. For example, my_list.append('orange') will add 'orange' to the end of my_list. You can also use insert(index, item) to add an item at a specific position.

What if I want to remove an item?

To remove an item, you can use the remove(item) method to remove the first occurrence of the item, or pop(index) to remove an item at a specific index. For example, my_list.remove('apple') will remove 'apple' from the list.

Can I sort a list?

Yes, you can sort a list using the sort() method, which sorts the list in place, or sorted(my_list) to return a new sorted list without modifying the original.
