How to tell the sex of my ball python

Question
What is the best possible way to tell the sex of my Ball Python(Royal Python or Python Regius)without takeing it to the vet or probeing it myself?

Answer
Hey Cainan,

Sexing a Ball Python is fairly easy.  all pythons and boas  have anal spurs.  they look like little spurs and  are about 2 - 3 inches from the end of the tail. Males have longer spurs than females.We actually believe the spurs are evolutionary hints or left over hind legs. Males also tend to have smaller heads than females, well i hope this was helpful.

                  thanks for the ?
