Hi @wai.mak,
Make sure the file is executable with ‘chmod +x simple.py’

I don’t know why “chmod +x simple.py” doesn’t work to me.

I’ve tried to say that it doesn’t work to me.
But they still answer the same question as using “chmod +x simple.py”

Oh! Very sorry. I think X is the number shown in the preview. But actually it’s a letter

It works !!
