我需要将one转换成1,two转换成2等等.
I need to convert one into 1, two into 2 and so on.
有没有办法通过库或类或任何东西来做到这一点?
Is there a way to do this with a library or a class or anything?
推荐答案
这段代码大部分是设置numwords dict,只在第一次调用时完成.
The majority of this code is to set up the numwords dict, which is only done on the first call.
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 print text2int("seven billion one hundred million thirty one thousand three hundred thirty seven") #7100031337
