怎么用函数调用的方式编程实现自动将这个整数转换为英文输出的形式

Question

请用函数调用的方式，实现当输入一个小于100的整数时，编程实现自动将这个整数转换为英文输出的形式。如输入的整数为76，则转换后的输出结果为：seventy six。

def unit_to_word(u):
    convert_table = {0: "zero",1: "one",2: "two",3: "three",4: "four",
        5: "five",6: "six",7: "seven",8: "eight",9: "nine"}
    return convert_table[u]
def tens_to_word(t):
    convert_table = {
        0: "",10: "ten", 11: "eleven",12: "twelve",13: "thirteen",14: "fourteen",
        15: "fifteen",16: "sixteen",17: "seventeen",18: "eighteen",19: "nineteen",
        2: "twenty",3: "thirty",4: "forty",5: "fifty",6: "sixty",7: "seventy",8: "eighty",
        9: "ninety"}
    if 9 < t < 20:
        return convert_table[t]
    else:
        tens = convert_table[t//10] + " " + unit_to_word(t%10)
        return tens


n=int(input('请输入：'))
print(tens_to_word(n))
