Consider everything that is not numeric to be a string. not char or text, but string.
Every string in python nomatter how many chars it has is a special set, that could be iterates through, or converted into a "normal" python list.
You can iterate through the string with for...in loop. Something like this:

>>> astring = "hdnjehc"
>>> for c in astring:
print (c + ' - ' + str(astring.count(c)))

Result:
h - 2
d - 1
n - 1
j - 1
e - 1
h - 2
c - 1
