Python comes with many modules, which are sets of programs other people have written that you can plug into your program, just like you can buy bread at the store without baking it yourself.
Python's even better than bread because most Python modules are free!
When you write a program, you are telling the computer to do something. Python For Dummies gives you step-by-step instructions that help you understand how to write the way a computer "thinks."
REMEMBER Unlike you, computers are pretty stupid. They can do only a few things.
All the actions that humans make them do are the result of the computer's doing those few things over and over, in different combinations, very quickly.
