如何显示输入号码的各个数字？

def display_digits(number):
    # 将数字转换为字符串
    number_str = str(number)
    # 遍历字符串中的每个字符，并将其转换回数字
    for digit in number_str:
        print(int(digit))

# 示例输入
input_number = 12345
display_digits(input_number)

def display_digits(number):
    try:
        number_str = str(number)
        for digit in number_str:
            print(int(digit))
    except ValueError:
        print("输入不是有效的数字")

# 示例输入
input_number = "12345a"
display_digits(input_number)

def display_digits(number):
    number_str = str(number)
    integer_part, decimal_part = number_str.split('.')
    print("整数部分：")
    for digit in integer_part:
        print(int(digit))
    if decimal_part:
        print("小数部分：")
        for digit in decimal_part:
            print(int(digit))

# 示例输入
input_number = 123.45
display_digits(input_number)
