python编写以函数，将数字金额转换为中文大写金额

好的，以下是Python代码实现：

# encoding:utf-8

def transition(number):
    if not isinstance(number, (int, float)):
        return '参数类型错误'
    if number > 999999999999.99 or number < 0:
        return '金额范围有误'
    unit_list = ['千', '百', '十', '']
    chinese_num_list = ['零', '一', '二', '三', '四', '五', '六', '七', '八', '九']
    chinese_unit_list = ['', '万', '亿', '兆']
    integral, decimal = str(number).split('.')
    integral_list = list(integral)
    integral_list.reverse()
    unit_index, zero_num, chinese_num, chinese_money = 0, 0, 0, ''
    for i, num in enumerate(integral_list):
        if num == '0':
            zero_num += 1
            if unit_index % 4 == 0:
                chinese_money = chinese_unit_list[unit_index // 4] + chinese_money
            if unit_index % 4 == 3:
                chinese_money = '零' + chinese_money
        else:
            if zero_num > 0:
                chinese_money = chinese_num_list[0] + chinese_money
            zero_num = 0
            chinese_num = chinese_num_list[int(num)]
            chinese_money = chinese_num + unit_list[unit_index % 4] + chinese_money
            if unit_index % 4 == 3:
                chinese_money = chinese_unit_list[unit_index // 4] + chinese_money
        unit_index += 1
    if zero_num > 0:
        chinese_money = chinese_num_list[0] + chinese_money
    chinese_money += '元'
    if decimal == '00':
        chinese_money += '整'
    else:
        chinese_money += chinese_num_list[int(decimal[0])] + '角'
        if decimal[1] != '0':
            chinese_money += chinese_num_list[int(decimal[1])] + '分'
    return chinese_money

if __name__ == '__main__':
    number = 123456789.33
    result = transition(number)
    print(result)

这个函数可以将数字金额转换为中文大写金额，例如将“123456789.33”转换为“壹亿贰仟叁佰肆拾伍万陆仟柒佰捌拾玖元叁角叁分”。
