The Python REPL

This is the Python REPL, also known as the Interactive Python Interpreter:

>>>

How can I tell it's the Python REPL?

Well, the prompt shows three greater than signs (>>>), which indicates that we're in the Python REPL.

Typing all of your code in the Python REPL is pretty limiting.

Our code disappears right after we've typed it. Also, if we'd like someone to be able to import our code as a module, they can't.

Definitions: program, script, command-line, editor

Let's make a Python program.
