检查给定数是否为素数，如果是素数，则查找该数的阶乘，如果不是素数，则打印该数的数字总和

Question

The sum of digit is running well, but Why is the factorial section not working? Is there any mistakes that I made with the if else, or the break?

NUM = int (input ("Enter a number "))
if NUM > 1:
    for x in range (2, NUM):
        if (NUM % x) == 0:  
            temp = NUM
            sod = 0
            while temp > 0:
                remainder = temp % 10  
                sod += remainder
                temp = temp//10
            print (sod)
        break
    else:
        factorial = 1
        for I in range (1, NUM + 1,1):
            factorial *= I
        print (factorial)        
else:
    temp = NUM
    sod = 0
    while temp > 0:
        remainder = temp % 10  
        sod += remainder
        temp = temp//10
    print (sod)

Answer 1

Your break statement on line 12 is outside the if statement, so the for loop will break after the first pass regardless of the value of NUM . Are you sure you didn't mean to indent the break another four spaces?

Answer 2

# example of factorial with prime numbers    
num = int(input("Enter a number"))
    factorial = 1
    if num%2 == 0:
        for i in range(1, num + 1):
            factorial = factorial*i
        print("The factorial of ",num," is",factorial)

Below code checks if the number is prime or odd number. if its prime it finds the factorial of that number and if its odd number then it sums the range of the number. Hope its what you were looking for.

NUM = int(input("Enter number here"))
if NUM > 0:
    if NUM % 2 == 0:
        factorial = 1
        for i in range(1, NUM +1):
            factorial = factorial*i
        print(factorial)
    else:
        sum_of_NUM = 0
        for x in range(NUM+1):
            sum_of_NUM += x
        print(sum_of_NUM)
else:
    print("something you want to put")
