Basics (Values and Assignment)

You will want to follow along with these examples. If something doesn’t work, or confuses you, ask!

>>> 5
5
>>> 5.0
5.0
>>> -5
-5

Now we’ll create a name (a variable) that points to a number:

>>> count = 5.0
>>> count
5.0
>>> count + 3
8.0

We can use the variable just as we would a number.

Exercise

  • Assign a number to a variable (call it whatever you like)
  • Print the results of adding/subtracting a few numbers to/from it
