Lists:

• Like arrays
• Can contain any type of variable & can contain as many variables as you want

mylist = []

mylist.append(1)

mylist.append(2)

mylist.append(3)

print(mylist[0])

• If you want to refer to something in the list then: list_"name"[0, 1, 2....]

Arithmetic Operators

• Modulo (%) operator

remainder = 11% 3

print(remainder) prints 2

• Double multiplication signs // power (ex. **2 is ^2 and **3 is ^3)
• Can print concatenating string

helloworld = "hello" + " " + "world"

print(helloworld) prints hello world

lotsofhellos = "hello" * 10

print(lotsofhellos) // prints hello 10 times in a row, no spaces no new lines
