Answer 1

Sololearn CP isn't a very fancy code runner.
For that we have to go to the outer world and seek better code runner.
Plainly saying, there are better people in coding than the creators of Sololearn.

Answer 2

There are many out there.
I recommend IDLE download Python (preferably 3.5+) and it comes with IDLE where you can create Python files and run code.
Or my school recommends PyCharm.
