MicroPython has an input and output console thats called the REPL, which stands for Read Evaluation Print Loop. This is because the REPL reads in commands, evaluates them, prints out the results to the console and then loops back to the reading in stage.

You will have noticed the REPL at the bottom of the screen, its where we see the output of all the code we’ve run so far.

You can type MicroPython code directly into the REPL, which is useful for quickly testing things or examining the attached MicroPython device.
