Get Familiar with Lists
Another crucial data type is called list! It is used to store variables:
list = [1, 3, 6, 'a', True]
You just need to put variables inside square brackets. You don't have restrictions, so in one list, you can store numbers, strings, and boolean data; that's all!
It is necessary to know how to get a specific element from the list to work with lists.
The list's first item has the index 0, the next one 1, and so on.
If we start from the end, the last item has the index -1, and the second-to-last has the index -2, and so on.

list_1 = ['P', 'y', 't', 'h', 'o', 'n']
print("The first item is", list_1[0])
print("The third item is", list_1[2])
print("The fifth item is", list_1[4])
print("The last item is", list_1[5])
# And using negative indexation
print("The first item is", list_1[-6])
print("The third item is", list_1[-4])
print("The fifth item is", list_1[-2])
print("The last item is", list_1[-1])

To pick up a draggable item, press the space bar.
While dragging, use the arrow keys to move the item.
Press space again to drop the item in its new position, or press escape to cancel.
