Python Program to Check a Number is a Spy Number

Write a Python program to check a number is a spy number or not using the for loop. For example, if the sum of digits equals the product of individual digits in a number, it is a spy number. In this Python spy number example, we used a while loop to divide the number into digits and find the sum and the product of the digits. The if statement checks whether the sum equals product, if true, spy number.

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 Program to Check a Number is a Spy Number

Python program to check whether a number is a spy number or not using recursion or recursive functions.

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.

This Python program prints the spy numbers from 1 to n or spy numbers within a range.

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
