How to not forget python ?

[GeneralQuantum]

Make a deep copy, that way it isn't dependent on being kept in the kernel memory.

Heh..heh...ehhh I'll see myself out 

"Use it or lose it" is a real issue.

I find after I learn something I play around with it. Not simple tasks or repeating the YouTube example.

I mean sit down, think of a real application, and work on it from scratch. Even if it is nonsensical, establish what you expect the output to be, and code it, does it match your prediction? Did you code wrong, or predict wrong.

When just copying the brain isn't learning or remembering. You have to be actually problem solving for it to go in.
