Using the interactive IPython alone is exciting only for a while. To write more complex programs, you need to store your instructions in programs, so that you can execute them later.
In the second part of the tutorial, you will learn a basic set of Python commands. Theoretically, they are sufficient to write any program on the planet (this is called Turing completeness).
Practically, you will need shortcuts that make programs prettier, faster, and less painful to write. We will save these shortcuts for the later parts.
The new Python commands cover:
- How to write to the screen.
- How to read from the keyboard.
- How to repeat instructions.
- How to store many items in a list.
- How to make decisions.
