• # Fail: checkio(1)

## Question related to mission Speech Module

When I try it all is right

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(num):
str_num = str(num)
length = len(str_num)

def get_dozen(str_num):
if str_num.startswith('1'):
return SECOND_TEN[int(str_num[1])]
elif not int(str_num):
return ''
elif str_num.endswith('0'):
return OTHER_TENS[int(str_num[0])-2]
else:
return '%s %s' % (OTHER_TENS[int(str_num[0])-2], FIRST_TEN[int(str_num[1])-1])

if length == 1:
print FIRST_TEN[num-1]
elif length == 2:
print get_dozen(str_num)
elif length == 3:
print "%s %s %s" % (FIRST_TEN[int(str_num[0])-1], HUNDRED, get_dozen(str_num[1:]))
else:
print -1

if __name__ == '__main__':
#These "asserts" using only for self-checking and not necessary for auto-testing
assert checkio(4) == 'four', "1st example"
assert checkio(133) == 'one hundred thirty three', "2nd example"
