!!! main.py

%%info
This is __Exercise 1__ of the [Micro Python Tutorial].
%%


The file (also sometimes called a "script") named {{main.py}} is special in MicroPython, in the sense that when you power-on the device and/or press the reset button, the contents of the {{main.py}} file are passed to the MicroPython interpreter and the program contained within main.py is executed. It's the ''entry point'' for running any application in Python.

%%filename main.py %%
%%python \\# this is a comment

print('hello world.')
print("hello again.")   # you can use single or double quotes
%%
