如何在列表中使用范围变量而不引发语法错误？

Question

a = range(20,30)
b = range(1000,5000)
list1 = [["range a",a],["range b",b]]
x = int(input())
for i in list1:
    if x in i:
        print("congratulations! input is in range"+i[0])
y = input()

程序立即关闭而不显示错误消息

下面的代码行起作用。你知道吗

     a = range(20,30)
     b = range(1000,5000)
     list1 = [a,b]
     x = int(input())
     for i in list1:
    if x in i:
         print("congratulasions! input is in range of ",i)
    y = input()
