In this kata we want to convert a string into an integer. The strings simply represent the numbers in words.
Examples:
- "one" => 1
- "twenty" => 20
- "two hundred forty-six" => 246
- "seven hundred eighty-three thousand nine hundred and nineteen" => 783919
Additional Notes:
- The minimum number is "zero" (inclusively)
- The maximum number, which must be supported is 1 million (inclusively)
- The "and" in e.g. "one hundred and twenty-four" is optional, in some cases it's present and in others it's not
- All tested numbers are valid, you don't need to validate them
dict1 = {'zero': 0, 'one': 1, 'two': 2, 'three': 3, 'four': 4, 'five': 5,
'six': 6, 'seven': 7, 'eight': 8, 'nine': 9, 'ten': 10, 'eleven': 11,
'twelve': 12, 'thirteen': 13, 'fourteen': 14, 'fifteen': 15, 'sixteen': 16,
'seventeen': 17, 'eighteen': 18, 'nineteen': 19, 'twenty': 20, 'thirty': 30,
'forty': 40, 'fifty': 50, 'sixty': 60, 'seventy': 70, 'eighty': 80, 'ninety': 90}
dict2 = {'hundred': '*100 ', 'thousand': '*1000 ', 'million': '*1000000 ', 'and': '+0 '}
en_string = 'one thousand'
temp = list(en_string.split(' '))
en_list = []
for i in range(len(temp)):
if '-' in temp[i]:
en_list += temp[i].split('-')
else:
en_list.append(temp[i])
# print(en_list)
str_num = '0'
for en in en_list:
if en in dict1:
str_num += '+' + str(dict1[en])
elif en in dict2:
str_num = str_num + dict2[en]
# print(str_num)
if '*1000 ' in str_num:
list_num = str_num.split('*1000 ')
if list_num[-1] == '':
res = 0
else:
res = eval(list_num[-1])
for n in list_num[0:-1]:
res = res + eval(n) * 1000
print(res)
else:
print(eval(str_num))
可能不全面，但是大部分是可以了
