easy to use MicroPython

from microbit import *
display.scroll("Hello, World!")

• Each line also has special semantics.

The form microbit import *

If you have been exposed to c before, you can understand by the library. All modules are existing code libraries. These libraries are imported from microbit. The second row

display.scroll("Hello, World!")

This also makes sense, telling microPython to use the display command to scroll the "helloworld" character number of the string. This display is a module in the microbit that represents the physical display of the device, with the display in quotes.

Now copy the code directly to your editor and burn it to your device. Can you change the character information? Give it a try!
