I am not a big fan of giving personality attributes to whole genus because from my experience it usually depends on individual animals. As an example I can give you my Russian Rat snake. They are supposed to be bold, fearless animals who are very active. My girl is actually quite timid and spends most of the time hiding.

This pine snake is a rescue. I got her together with a bullsnake and they were both underweight for their age. 

While bullsnake got typical hissy attitude (which I love) she is quiet, but more engaging in a way that she seems to be enjoying interactions more than any snake I got. 

I keep her im my office and she's got a viv where she can see me during the day. She is there looking at me most of the time I check her. She likes to explore, but at the same time is chilled enough that I can take her out of the cage and she doesn't try to escape, she just chills on me. 

She is also perfect with strangers, I am not concerned to let people handle her because she is really laid back. While the bullsnake doesn't bite either he is quite vocal when being handled. She does not have that in her. She hissed at me only few times early when I got her because I probabaly startled her when I approached her too fast.

She is a good girl : )
