More Information
Python's interactive mode is often referred to as the REPL (Read-Eval-Print Loop) because it reads a statement, evaluates it, prints the result, and then loops back for another statement. It is useful for testing snippets of code quickly.
Tips
A common mistake is to expect statefulness across sessions; however, once the interactive session is exited, all the variables and functions are lost unless saved explicitly.
