List
Lists in Python represent ordered sequences of values.
Lists are "mutable", meaning they can be modified "in place".
# list of integer type
primes = [2, 3, 5, 7]
# list of string type
planets =
['Mercury', 'Venus', 'Earth', 'Mars', 'Jupiter', 'Saturn', 'Uranus', 'Neptune']
# list of lists
hands = [['J', 'Q', 'K'], ['2', '2', '2'], ['6', 'A', 'K']]
# list of different types
my_favourite_things = [32, 'raindrops on roses', help]Slicing
planets[0:3] #['Mercury', 'Venus', 'Earth']
