Mu editor doesn't flag blatant errors?

[mprogers]

Hello,

I just started looking at MicroPython, and the online editor (http://python.microbit.org/v/1). It doesn't seem to spot any errors, for example, I wrote:

from microbit import *

while
while True:
display...
display.scroll('Hello, World!')
display.show(Image.HEART)
sleep(2000)

and there were no complaints from the editor, and I was able to then download a hex file.

Am I missing something here? What's the best way to write MicroPython code? My audience would be high school and non-CS majors at university.

You might get a better response if you directed this question at the mu maintainers.
