!!! main.py

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

The file {{main.py}} is special in MicroPython, only in the sense that when you power-on the device and/or press the reset button, the main.py file is executed.

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

print('hello world.')
print("hello again.")
%%

There is a structure in Python called a {{try-except-finally}} __block__, which is ideal for a main.py file:

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

try:

    print('hello world.')
^^^^  🠈 remember to indent the insides of your blocks by 4 characters!

except Exception as ex:
    print('an error occurred: {}'.format(ex))
finally:
    print('complete.')
%%
