... how many positive integers less than n have digits that sum up to m:
In [197]: def prttn(m, n):
tot = 0
for i in range(n):
s = str(i)
sum = 0
for j in range(len(s)):
sum += int(s[j])
if sum == m:
tot += 1
return tot
.....:
In [207]: prttn(25, 10000)
Out[207]: 348
any suggestion for pythonizin' it?
bye
