Yup...it works..but now i have to create a dictionary of 'a' and 'm',
ie... "Xaa" and "Xma" string, key:value pairs so i can use other
functions on the Xaa, Xma variables by iterating over them and
retrieving the values from the variables. I think if i just input Xaa
and Xma, only the values associated with those variables will go into
the dictionary and ill just be iterating over nonsence.....

atomsmasses = {}

def monoVarcalc(atom):
a = atom + 'aa'
m = atom + 'ma'
atomsmasses[a]=m
Xaa = a.strip('\'')
Xma = m.strip('\'')
Xma = pt.get(atom)
if DS1v.get(atom) != None:
Xaa = DS1v.get(atom)
else:
Xaa = 0
return Xaa, Xma

Caa, Cma = monoVarcalc('C')
Oaa, Oma = monoVarcalc('O')
Haa, Hma = monoVarcalc('H')
Naa, Nma = monoVarcalc('N')
Saa, Sma = monoVarcalc('S')
Claa, Clma = monoVarcalc('Cl')
Braa, Brma = monoVarcalc('Br')
Znaa, Znma = monoVarcalc('Zn')



i think? :)
thanks
