输入一个三位数判断是否是水仙花数

num = input("please input the number:")
num1 = 0
for i in num:
    i = int(i)
    num1 += i * i *i
if num1 == int(num):
    print(f"{num} is right")

100-1000之间一共有几个水仙花数

i= 0
for num in range(100,1000):
    high = num // 100
    middle = num // 10 % 10
    low = num % 10
    num1 = high ** 3 + middle ** 3 +low ** 3
    if num == num1:
        i +=1
        print(f"{num} is right")
print(f"total count is {i}")
