I was bitten today by a small black insect with yellow stripes, I think it was a spider but I am not too sure.

My guess is that this spider you saw was either a Jumping Spider (quite possibly a Daring Jumping Spider) or a Parson Spider.

You can make Halloween spider legs out of black pipe cleaners for small decorations. Halloween costume spider legs can be made of black material or black tights.
It depends on which species of snake are you talking about. If it's is a Cobra, King Cobra and Brown snake, a black widow doesn't stand a chance. Most snakes, however, are not venomous at all. P.S. A black widow isn't the most venomous spider, there are also the red back spider and funnel-web spider who are much more dangerous.
