In the previous article, we have discussed Python Program to Find the 2nd Largest Digit in a Given Number
Given a number, and the task is to check if the sum of even digits of a number is divisible by 4 and the sum of odd digits of a given number is divisible by 3.

Examples:

Example1:

Input:

Given Number = 123452

Output:

yes, the even digits sum and odd digits sum of a given number{ 123452 } is divisible by 4 and 3 respectively.

Example2:

Input:

Given Number = 4532176

Output:

No, the even digits sum and odd digits sum of a given number{ 4532176 } is not divisible by 4 and 3 respectively.

Program to Find Even Digits Sum and Odd Digits Sum Divisible by 4 and 3 Respectively in Python:

Below are the ways to check if the sum of even digits of a number is divisible by 4 and the sum of odd digits of a given number is divisible by 3.

Method #1: Using For Loop (Static Input)

Approach:

  • Give the number as static input and store it in a variable.
  • Convert the given number to a string using the str() function and store it in another variable.
  • Create a list of digits say “digtslst” using map(),list(),int functions.
  • Store it in another variable.
  • Take a variable say “evn_sum” and initialize it with 0.
  • Take another variable say “od_sum” and initialize it with 0.
  • Loop in the above list of digits until the length of the “digtslst” using the for loop.
  • Check if the element of the “digtslst” is even or not using the if conditional statement.
  • If the statement is true, then add the element of the “digtslst” to the “evn_sum” and store it in the same variable evn_sum.
  • If the statement is false, then add the element of the “digtslst” to the “od_sum ” and store it in the same variable od_sum.
  • Check if the evn_sum modulus 4 is equal to 0 and od_sum modulus 3 is equal to 0 using the if conditional statement.
  • If the statement is true, print “yes, the even digits sum and odd digits sum of a given number are divisible by 4 and 3 respectively.
  • If the statement is false, print “No, the even digits sum and odd digits sum of a given number are not divisible by 4 and 3 respectively.
  • The Exit of the Program.

Below is the implementation:

# Give the number as static input and store it in a variable.
numb = 123452
# Convert the given number to string using the str() function.
stringnum = str(numb)
# Create a list of digits say "digtslst" using map(),list(),int functions.
digtslst = list(map(int, stringnum))
# Take a variable say "evn_sum" and initialize it with 0.
evn_sum = 0
# Take another variable say "od_sum" and initialize it with 0.
od_sum = 0
# Loop in the above list of digits until the length of the "digtslst" using the for loop.
for itr in range(len(digtslst)):
    # Check if the element of the "digtslst" is even or not using the if conditional statement.
    if(digtslst[itr] % 2 == 0):
     # If the statement is true, then add the element of the "digtslst" to the "evn_sum"
        # and store it in the same variable evn_sum.
        evn_sum += digtslst[itr]
    else:
        # If the statement is false, then add the element of the "digtslst" to the "od_sum"
        # and store it in the same variable od_sum.
        od_sum += digtslst[itr]
# Check if the evn_sum modulus 4 is equal to 0 and od_sum modulus 3 is equal to 0
# using the if conditional statement.
if(evn_sum % 4 == 0 and od_sum % 3 == 0):
  # If the statement is true, print "yes, the even digits sum and odd digits sum of a
    # given number are divisible by 4 and 3 respectively.
    print(
        "yes, the even digits sum and odd digits sum of a given number{", numb, "} is divisible by 4 and 3 respectively.")
else:
 # If the statement is false, print "No, the even digits sum and odd digits sum
    # of a given number are not divisible by 4 and 3 respectively.
    print(
        "No, the even digits sum and odd digits sum of a given number{", numb, "} is not divisible by 4 and 3 respectively.")

Output:

yes, the even digits sum and odd digits sum of a given number{ 123452 } is divisible by 4 and 3 respectively.

Method #2: Using For loop (User Input)

Approach:

  • Give the number as user input using the int(input()) function and store it in a variable.
  • Convert the given number to a string using the str() function and store it in another variable.
  • Create a list of digits say “digtslst” using map(),list(),int functions.
  • Store it in another variable.
  • Take a variable say “evn_sum” and initialize it with 0.
  • Take another variable say “od_sum” and initialize it with 0.
  • Loop in the above list of digits until the length of the “digtslst” using the for loop.
  • Check if the element of the “digtslst” is even or not using the if conditional statement.
  • If the statement is true, then add the element of the “digtslst” to the “evn_sum” and store it in the same variable evn_sum.
  • If the statement is false, then add the element of the “digtslst” to the “od_sum ” and store it in the same variable od_sum.
  • Check if the evn_sum modulus 4 is equal to 0 and od_sum modulus 3 is equal to 0 using the if conditional statement.
  • If the statement is true, print “yes, the even digits sum and odd digits sum of a given number are divisible by 4 and 3 respectively.
  • If the statement is false, print “No, the even digits sum and odd digits sum of a given number are not divisible by 4 and 3 respectively.
  • The Exit of the Program.

Below is the implementation:

# Give the number as user input using the int(input()) function and store it in a variable.
numb = int(input("Enter some random number = "))
# Convert the given number to string using the str() function.
stringnum = str(numb)
# Create a list of digits say "digtslst" using map(),list(),int functions.
digtslst = list(map(int, stringnum))
# Take a variable say "evn_sum" and initialize it with 0.
evn_sum = 0
# Take another variable say "od_sum" and initialize it with 0.
od_sum = 0
# Loop in the above list of digits until the length of the "digtslst" using the for loop.
for itr in range(len(digtslst)):
    # Check if the element of the "digtslst" is even or not using the if conditional statement.
    if(digtslst[itr] % 2 == 0):
     # If the statement is true, then add the element of the "digtslst" to the "evn_sum"
        # and store it in the same variable evn_sum.
        evn_sum += digtslst[itr]
    else:
        # If the statement is false, then add the element of the "digtslst" to the "od_sum"
        # and store it in the same variable od_sum.
        od_sum += digtslst[itr]
# Check if the evn_sum modulus 4 is equal to 0 and od_sum modulus 3 is equal to 0
# using the if conditional statement.
if(evn_sum % 4 == 0 and od_sum % 3 == 0):
  # If the statement is true, print "yes, the even digits sum and odd digits sum of a
    # given number are divisible by 4 and 3 respectively.
    print(
        "yes, the even digits sum and odd digits sum of a given number{", numb, "} is divisible by 4 and 3 respectively.")
else:
 # If the statement is false, print "No, the even digits sum and odd digits sum
    # of a given number are not divisible by 4 and 3 respectively.
    print(
        "No, the even digits sum and odd digits sum of a given number{", numb, "} is not divisible by 4 and 3 respectively.")

Output:

Enter some random number = 4532176
No, the even digits sum and odd digits sum of a given number{ 4532176 } is not divisible by 4 and 3 respectively.
