阿拉伯数字转大写汉字的python代码

以下是将阿拉伯数字转换为大写汉字的Python代码：

# coding=utf-8

chinese_num = {
    '0': '零',
    '1': '壹',
    '2': '贰',
    '3': '叁',
    '4': '肆',
    '5': '伍',
    '6': '陆',
    '7': '柒',
    '8': '捌',
    '9': '玖'
}

chinese_unit = {
    0: '',
    1: '拾',
    2: '佰',
    3: '仟',
    4: '万',
    5: '拾',
    6: '佰',
    7: '仟',
    8: '亿',
    9: '拾',
    10: '佰',
    11: '仟'
}

def num_to_chinese(num):
    num_str = str(num)
    length = len(num_str)
    result = ''
    for i in range(length):
        digit = int(num_str[i])
        unit = length - i - 1
        if digit != 0:
            result += chinese_num[str(digit)] + chinese_unit[unit]
        else:
            if unit == 4 or unit == 8:
                result += chinese_unit[unit]
            elif result[-1] != chinese_num['0']:
                result += chinese_num['0']
    if result[-1] == chinese_num['0'] and len(result) > 1:
        result = result[:-1]
    return result

if __name__ == '__main__':
    num = 123456789
    print(num_to_chinese(num))  # 一亿二千三百四十五万六千七百八十九

该代码将阿拉伯数字转换为大写汉字，并且考虑了0的位置以及亿、万的单位。
