Python 程序：檢查數字是不是間諜數字

編寫一個 Python 程序來檢查一個數字是否是間諜數字，或者是否使用 for 循環。例如，如果數字的總和等於一個數字中各個數字的乘積，那麼它就是一個間諜號。在這個 Python 間諜號的例子中，我們使用了一個 while 循環來將數字分成數字，並找到這些數字的總和和乘積。if 語句檢查總和是否等於乘積，如果為真，則檢查間諜號。

Number = int(input("Enter the Number to Check Spy Number = "))
Temp = Number
Sum = 0
prod = 1

while Temp > 0:
    lastDigit = Temp % 10
    Sum = Sum + lastDigit
    prod = prod * lastDigit
    Temp = Temp // 10

print("The Sum of the Digits     = %d" %Sum)
print("The Product of the Digits = %d" %prod)

if Sum == prod:
    print("\n%d is Spy Number." %Number)
else:
    print("%d is Not a Spy Number." %Number)

Python 程序使用遞歸或遞歸函數來檢查一個數字是否是間諜數字。

total = 0
prod = 1
reminder = 0
def spyNumber(number):
    global reminder, total, prod
    if(number > 0):
        reminder = number % 10
        total = total + reminder
        prod = prod * reminder
        spyNumber(number // 10)
        return total, prod
    else:
        return 0

Number = int(input("Enter the Number to Check Spy Number = "))
total, prod = spyNumber(Number)

print("The Sum of the Digits     = %d" %total)
print("The Product of the Digits = %d" %prod)

if total == prod:
    print("\n%d is Spy Number." %Number)
else:
    print("%d is Not a Spy Number." %Number)

Enter the Number to Check Spy Number = 1421
The Sum of the Digits     = 8
The Product of the Digits = 8

1421 is Spy Number.

這個 Python 程序列印從 1 到 n 的間諜號或者某個範圍內的間諜號。

MinSpy = int(input("Please Enter the Minimum Spy Value: "))
MaxSpy = int(input("Please Enter the Maximum Spy Value: "))

for i in range(MinSpy, MaxSpy + 1):
    Temp = i
    Sum = 0
    prod = 1
    while Temp > 0:
        lastDigit = Temp % 10
        Sum = Sum + lastDigit
        prod = prod * lastDigit
        Temp = Temp // 10

    if Sum == prod:
        print(i, end = '   ')

Please Enter the Minimum Spy Value: 1
Please Enter the Maximum Spy Value: 10000
