There is no recognized set of symbols for ball pythons.
Ideally, each mutant has a unique name and a unique symbol based on the name. "A is for apple" is common in alphabet books. So, "a is for albino" can start your genetics symbols.
Recessive mutant symbols are lower case. Dominant and codominants have the first letter uppercase.
Examples of possible symbols for mutant genes:
a = albino (a recessive)
P = pastel (a codominant)
pi = piebald (a recessive)
Ps = pinstripe (a codominant, I think)
The plus character, either by itself of as a superscript, is the internationally recognized symbol for the wild type or normal gene at each location in the genome. Unfortunately, kingsnake.com filters out several seldom-used characters, including the plus. 
a with plus for a superscript = the normal version of the albino mutant gene.
P with plus for a superscript = the normal version of the pastel mutant gene
pi with plus for a superscript = the normal version of the piebald mutant gene
Ps with plus for a superscript = the normal version of the pinstripe mutant gene
