"Practice Diligently"🤔🤔 Please who knows the meaning of those two words

Question

My lecturer said those two words to me while I was working with python today.

Answer 1

~ swim ~ thanks...I now get it

Answer 2

Mirielle he just said it through the window of our classroom and passed. Being alone, I decided to share it here, to get someone's view on it,
I actually did copy a code and used maybe that's his reason for saying them.
Thanks, though, for the concern.
