如何在python中将数字字转换为数字

我想把用文字表示的数字转换成数字

比如说,，

三万四千四百五十

转换为相应的数值

34450

。 还有一些模糊转换，如“请支付三万四千四百五十美元”然后输出为

34450

对于从数字到单词的转换，请尝试“num2words”软件包：

对于words to num，我从这里的代码稍微调整了代码：

->五十亿贰拾贰万贰仟贰佰贰拾叁元贰角捌分

->50002223.28

我要求的是单词到数字，而不是数字到单词我已经更新了答案我认为它无法转换小数点@Oxymoron88你能举一个例子说明单词在小数点处的外观吗？如果它像“十一点六三”，你只需要把字符串和点分开，把单词和数字分开，用小数点的数字把它们连在一起。它从来没有说成十一点六三，而是像十一点六三，那么塞纳里奥会是怎样的呢，不是数字到单词我已经更新了答案我不认为它能够转换小数点@Oxymoron88你能举个例子说明单词在小数点处的外观吗？如果它像“十一点六三”，你只需要把字符串和点分开，把单词和数字分开，用小数点将它们连在一起。它从来没有说成十一点六三，而是像十一点六三，senario会是怎样的呢？这是一个愚蠢的实现：=）这是一个愚蠢的实现：=）

from num2words import num2words

def text2int(textnum, numwords={}):
    if not numwords:
      units = [
        "zero", "one", "two", "three", "four", "five", "six", "seven", "eight",
        "nine", "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen",
        "sixteen", "seventeen", "eighteen", "nineteen",
      ]

      tens = ["", "", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety"]

      scales = ["hundred", "thousand", "million", "billion", "trillion"]

      numwords["and"] = (1, 0)
      for idx, word in enumerate(units):    numwords[word] = (1, idx)
      for idx, word in enumerate(tens):     numwords[word] = (1, idx * 10)
      for idx, word in enumerate(scales):   numwords[word] = (10 ** (idx * 3 or 2), 0)

    current = result = 0
    for word in textnum.split():
        if word not in numwords:
          raise Exception("Illegal word: " + word)

        scale, increment = numwords[word]
        current = current * scale + increment
        if scale > 100:
            result += current
            current = 0

    return result + current

#### My update to incorporate decimals
num = 5000222223.28
fullText = num2words(num).replace('-',' ').replace(',',' ')
print fullText

decimalSplit = fullText.split('point ')

if len(decimalSplit) > 1:
    decimalSplit2 = decimalSplit[1].split(' ')
    decPart = sum([float(text2int(decimalSplit2[x]))/(10)**(x+1) for x in range(len(decimalSplit2))])
else:
    decPart = 0

intPart = float(text2int(decimalSplit[0]))

Value = intPart + decPart

print Value
