Welcome to the forum and the wonderful world of snake keeping!!
I'm from the school that new snakes should be allowed to settle in and handling should wait until the snake has eaten three consecutive meals without refusal... especially for now keepers. Experienced keepers are better equipped to identify stress.
At this point, I would suggest just watching. Try to watch your BP and learn mannerisms, body language etc...
Once ypur snake has eaten three consecutive meals without refusal, start handling a few times per week. Keep sessions short, 5-10 minutes. This will allow both you and the snake to acclimate to one another gradually. As you and your new pet grow more comfortable with each other gradually increase the length of handling sessions a little at a time.
Avoid handling on feed days, for 48 hours after feeding and while the snake is in shed.
As for handling, always wash ypur hands prior to handling. Also, it's important to understand that predators attack from above. So, don't come in like a predator. Move slowly and try to come in from the side and scoop the snake from below.
Let the snake dictate it's movements, don't restrict the snake. But also make sure the snake is well supported and not fearful of falling. Let the snake explore your hands and arms, familiarizing himself with you.
When it's time to put the snake back in the enclosure set the snake down gently and mind a let the snake crawl off of you.
Hope this helps!
