I'd like to count how many specific characters appear in the string. What's the easiest way?

ex) mystring = "aaabcc" When

a->3 b->1 c->2

Returns the strong result of sub within the range of [start, end].

m = "kkkkaa"

print "m.count('kk'):\t\t", m.count("kk")
print "m.count('a'):\t\t", m.count("a")
print "m.count('a', 0, 2):", m.count("a", 0, 2)

Result:

m.count('kk'):      2
m.count('a'):       2
m.count('a', 0, 2): 0
