Write a Python program to Calculate the sum of the digits in an integer

Python program to Calculate the sum of the digits in an integer

Method 1:-

num = int(input("Input a four digit numbers: "))
a  = num //1000
a1 = (num - a*1000)//100
a2 = (num - a*1000 - a1*100)//10
a3 = num - a*1000 - a1*100 - a2*10
print("The sum of digits in the number is", a+a1+a2+a3)

output:-

Input a four digit numbers: 1246

The sum of digits in the number is 13

Method 2:-

def sumDigits(no):
    return 0 if no == 0 else int(no % 10) + sumDigits(int(no / 10)) 
   
# Driver code
n = int(input("Input a four digit numbers: "))
print(sumDigits(n))

output:-

Input a four digit numbers: 123
6

Method 3:-
def getSum(n):
    
    sum = 0
    while (n != 0):
       
        sum = sum + (n % 10)
        n = n//10
       
    return sum
   
n = int(input("Input a four digit numbers: "))
print(getSum(n))

output:-

Input a four digit numbers: 14545
19

Method 4:-

def getSum(n):
    
    sum = 0
    for digit in str(n): 
      sum += int(digit)      
    return sum
   
n = int(input("Input a four digit numbers: "))
print(getSum(n))

output:-

Input a four digit numbers: 13243
