题目：中文数字转换为阿拉伯数字，如下：
输入：
十一万亿五千三百万三千二百零七
输出：
11000053003207
思路：
-
- 先写一个处理
10000以下的转换函数，如下代码的num_process()
- 先写一个处理
-
- 以
亿和万分别进行切分，如下代码的yi_wan_process()
- 以
num_map = {'零': 0, '一': 1, '二': 2, '三': 3, '四': 4, '五': 5, '六': 6, '七': 7, '八': 8, '九': 9}unit_map = {'十': 10, '百': 100, '千': 1000, '万': 10000, '亿': 100000000}# 处理 一万 以下的情况
def num_process(chinese_number):if not chinese_number:return 0result = 0first_unit = chinese_number[0] in unit_mapnum = 0for index, char in enumerate(chinese_number):if char in num_map:num = num_map[char]if index == len(chinese_number) - 1:result += numelif char in unit_map:if index == 0 and first_unit:result += unit_map[char]else:result += num * unit_map[char]num = 0return result# 以 亿 和 万 进行切分
def yi_wan_process(chinese_number, split_unit):if not chinese_number:return 0result = 0before, after = "", chinese_numberindex = chinese_number.find(split_unit)if index != -1:before = chinese_number[:index]after = chinese_number[index + 1:]if split_unit == "亿":result += yi_wan_process(before, "万") * unit_map[split_unit]result += yi_wan_process(after, "万")elif split_unit == "万":result += num_process(before) * unit_map[split_unit]result += num_process(after)return resultdef chinese_to_arabic(chinese_number):if not chinese_number:return 0return yi_wan_process(chinese_number, "亿")if __name__ == "__main__":chinese_number = "十一万亿五千三百万三千二百零七"result = chinese_to_arabic(chinese_number)print(chinese_number, result) # 十一万亿五千三百万三千二百零七 11000053003207
