用python将输入的阿拉伯数字转化为中文大写数字

可以使用以下代码实现：

def to_chinese_numeral(num):
    chinese_numeral = ""
    numeral_dict = {0: "零", 1: "壹", 2: "贰", 3: "叁", 4: "肆", 5: "伍", 6: "陆", 7: "柒", 8: "捌", 9: "玖"}
    unit_list = ["", "拾", "佰", "仟", "万", "亿"]
    num_str = str(num)
    num_len = len(num_str)

    for i in range(num_len):
        n = int(num_str[i])
        u = unit_list[num_len - i - 1]
        if n != 0:
            chinese_numeral += numeral_dict[n] + u
        else:
            if chinese_numeral[-1:] != "零":
                chinese_numeral += "零"
            if u == "万" or u == "亿":
                chinese_numeral += u

    if chinese_numeral[-1:] == "零" and chinese_numeral[-2:-1] == "零":
        chinese_numeral = chinese_numeral[:-1]

    return chinese_numeral

该函数将输入的阿拉伯数字转化为中文大写数字，并返回一个字符串。例如：

>>> to_chinese_numeral(123456789)
'壹亿贰仟叁佰肆拾伍万陆仟柒佰捌拾玖'
>>> to_chinese_numeral(100000000)
'壹亿'
>>> to_chinese_numeral(1001)
'壹仟零壹'
