>>> <---- type stuff when you see this thingy

###Basic Math

>>> 8+8

16

>>> 8-4

4

>>> 2*8

16

>>> 4/2

2

>>> 2**3

8

###Variables/Strings >>> apples="bananas"

>>> apples

'bananas'

>>> x ='red'

>>> y ='rum'

>>> x+y

'redrum'

###Slicing/Indexing

>>> x[0]

'r'

>>> x[1]

'e'

>>> x[2]

'd'

Each number represents an index or address for each letter in the string. It starts with 0

>>> x[0:2]

're'

A slice tells the computer to print all of the letters from the start(0) to the end (2)

>>> x[0:3]

'red'

>>> x[::-1]

'der'

x[start : end : steps]

###print() input()

>>> print("HelloWorld")

HelloWorld

>>> print(x)

red

You can also print a slice:

>>> print(x[0:2])

re

>>> x= input("What do you want x to be?")

What do you want x to be? 'happy'

>>> x

'happy'
