您必须对以下内容进行字符串比较此

You would have to do string comparisons for this

for number in numbers:
    if '4' in str(number):
        print('{} True'.format(number))
    else:
        print("False")

问数字 4 是否在另一个数字中并没有什么意义（除非您对 in有一些特殊的定义） ）

It isn't really meaningful to ask if the number 4 is "in" another number (unless you have some particular definition of "in" in mind)
