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.

Using For Loop (Static Input)
Using For loop (User Input)

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.
