Just keep hides and stuff the cage with some snake safe clutter.

I started my ball python in a similar sized enclosure she was about 100g at the time. As long as you provide the needs of the ball python like many others have said, you should be okay.

This also depends on the BP though. My first BP is a very sweet and chillax snake that pretty much takes everything I throw at her and shrugs it off not showing much reaction to environmental factors at all. I have had to use her sheds as indicators xD. Because no matter what she eats like a champ.

My suggestion is to get a good amount of pangaea hides(4-5) and kind of clutter them evenly then use some fake plants to clutter the cage(I have heard this helps have not actually used it myself)
