• # Strange error output.

I would like to give some feedback about output from Checkio assertions.
It says:
Right result: 'one hundred'
I have no idea what's wrong.

My code:

```FIRST_TEN = ["one", "two", "three", "four", "five", "six", "seven",
"eight", "nine"]
SECOND_TEN = ["ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen",
"sixteen", "seventeen", "eighteen", "nineteen"]
OTHER_TENS = ["twenty", "thirty", "forty", "fifty", "sixty", "seventy",
"eighty", "ninety"]
HUNDRED = "hundred"

def checkio(number):
repr = {"0": "", "00": "", "000": ""}
for i in range(1, 10):
repr[str(i)] = FIRST_TEN[i-1]
for i in range(10, 20):
repr[str(i)] = SECOND_TEN[i-10]
for i in range(20, 91, 10):
repr[str(i)] = OTHER_TENS[i // 10 - 2]

num = str(number)[::-1]
string = ""

skip = 0
for i, x in enumerate(num):
if skip > 0:
skip -= 1
continue

if len(num) > i+2:
string += repr[num[i+2]] + " " + HUNDRED + " " + checkio(num[i+1] + x)
skip = 2

elif len(num) > i+1:
if num[i+1] == "1":
string += repr[num[i+1] + x]
else:
m = repr[num[i+1] + "0"] + " " + repr[x]

if len(m) > 0 and m == " ":
m = m[1:]
if len(m) > 0 and m[-1] == " ":
m = m[:-1]

string += m
skip = 1

else:
string += repr[x]

return string

if __name__ == '__main__':
#These "asserts" using only for self-checking and not necessary for auto-testing
