any suggestion for pythonizin' it?
This is how I would do it:
def prttn(m, n):
"""How many positive integers less than n have digits that sum up to m"""
total = 0
for testval in range(n):
sumofdigits = sum(int(char) for char in str(testval))
this line gives me this:
TypeError: 'int' object is not callable
is it some new feature in >2.5 ?
if sumofdigits == m:
total += 1
return total
I added a docstring to the function, saying what it does, and what the
arguments are supposed to represent. I also moved the
convert-to-string-and-sum-the-digits logic into a single generator
expression that's passed to the builtin sum function. Oh, and I tried
to use slightly more expressive variable names.
