# Discussion on: Daily Challenge #260 - Subtract the Sum

Boris Quiroz • Edited

Some python-that-can-be-improved:

``````elements = [
"1-kiwi",
"2-pear",
"3-kiwi",
"4-banana",
"5-melon",
"6-banana",
"7-melon",
"8-pineapple",
"9-apple",
"10-pineapple",
"...",
"100-pineapple"
]

def substractSum(n):
if 10 <= n <= 10000:
sum_n = 0
for digit in str(n):
sum_n += int(digit)

result = n - sum_n

while result > 100:
for digit in str(n):
sum_n += int(digit)
result = n - sum_n

print(n, result, elements[result-1])
else:
print("{}: Use value between 10 and 10000".format(n))

substractSum(9)
substractSum(10)
substractSum(31)
substractSum(110)
substractSum(111)
substractSum(325)
substractSum(1204)
substractSum(1316)
substractSum(2888)
substractSum(10000)
substractSum(10001)

``````

Output of the above:

``````❯ python 260.py
9: Use value between 10 and 10000
10 9 9-apple
31 27 27-apple
110 100 100-pineapple
111 99 99-apple
325 95 95-melon
1204 98 98-pineapple

2888 80 80-cucumber
