将数字单词转换为整数
通常，需要转换表示为文本的数字单词（例如，“一”、“二” ") 转化为相应的整数
解决方案：
为了促进这种转换，引入了一个名为 text2int 的 Python 函数，它利用数字词 (numwords) 的综合字典来映射文本表示为整数。这是实现：
def text2int(textnum, numwords={}):
if not numwords:
# Initialize the numwords dictionary only on the first call
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示例：
考虑以下输入：“70亿1亿31337”
print text2int("seven billion one hundred million thirty one thousand three hundred thirty seven") # 7100031337以上是如何在 Python 中将数字单词转换为整数？的详细内容。更多信息请关注PHP中文网其他相关文章！
