To create a variable, you need to do two things:
- Declare the variable
- Assign a value (data) to the variable
As an example, let's make a variable, foo, and assign it the value bar. The code to do this would be:
foo = "bar"
That single line of code declares a variable and assigns a string value to the variable. If you break it into several parts, the actual line of code consists of the following pieces:
Why are there quote marks around bar? What is a string value? These questions will be answered in the coming two sections, Basic types and String types.
