Variables

So what is a variable?

A variable can best be described as a box.

We have a label on the box and that's the variable's name,

Then we have something in the box and that's the variable's data or content.

So when we want to make a new variable we need to give it a name and then what ever data we want to store...

my_name = "Beanzilla"

In this example, we have a variable called my_name that is assigned the data "Beanzilla".

So how do we access it?

print(my_name)

Beanzilla

Ok what else can we do?

my_fav_number = 9
my_least_fav_number = 1
sum = my_fav_number + my_least_fav_number
print(sum)

10

In the above example we now show you can add 2 (or more) variables together to make a 3rd variable...

But thats not all!

myself = {"name": "Beanzilla", "pets_name": "Fishstick"}
print(myself["name"])

Beanzilla

What is this?

Let's create a list of some data types in python:

• my_string = ""
• my_int = 0
• my_dict = {}
• my_list = []
• my_float = 0.0

And of course there is more data types out there in python.

So the above example is a dict or dictonary, it stores key and value...

myself = {"name": "Beanzilla", "pets_name": "Fishstick"}
# We have 2 keys, name and pets_name
# We have 1 value for each key
# name = Beanzilla
# pets_name = Fishstick
print(myself)

{'name': 'Beanzilla', 'pets_name': 'Fishstick'}

Ugly... but if we give it a key it will print it nicely...

print(myself["pets_name"])

Fishstick
