创建一个函数，该函数接受一个从1到10的数字，并返回其对应的罗马数字。
def get_roman_numeral(number):
    if number == 1:
        return "I"
    elif number == 2:
        return "II"
    elif number == 3:
        return "III"
    elif number == 4:
        return "IV"
    elif number == 5:
        return "V"
    elif number == 6:
        return "VI"
    elif number == 7:
        return "VII"
    elif number == 8:
        return "VIII"
    elif number == 9:
        return "IX"
