Oddish or Evenish

Write a Python program to check whether a given number is odd or even.

A number is called "Oddish" if the sum of all of its digits is odd, and a number is called "Evenish" if the sum of all of its digits is even.

Sample Solution:

Python Code:

# Define a function named oddish_evenish_num that checks whether the sum of digits of a number (n) is odd or even.
def oddish_evenish_num(n):
    # Use the sum function to calculate the sum of all digits in the number.
    # Check if the sum is odd and return 'Oddish', otherwise return 'Evenish'.
    return 'Oddish' if sum(map(int, str(n))) % 2 else 'Evenish'

# Test the function with different numbers and print the results.

# Test case 1
n = 120
print("Original Number:", n)
print("Check whether the sum of all digits of the said number is odd or even!")
print(oddish_evenish_num(120))

# Test case 2
n = 321
print("\nOriginal Number:", n)
print("Check whether the sum of all digits of the said number is odd or even!")
print(oddish_evenish_num(321))

# Test case 3
n = 43 
print("\nOriginal Number:", n)
print("Check whether the sum of all digits of the said number is odd or even!")
print(oddish_evenish_num(43))

# Test case 4
n = 4433
print("\nOriginal Number:", n)
print("Check whether the sum of all digits of the said number is odd or even!")
print(oddish_evenish_num(4433))

# Test case 5
n = 373
print("\nOriginal Number:", n)
print("Check whether the sum of all digits of the said number is odd or even!")
print(oddish_evenish_num(373))

Sample Output:

Original Number 120
Check whether the sum of all digits of the said number is odd or even!
Oddish
Original Number 321
Check whether the sum of all digits of the said number is odd or even!
Evenish
Original Number 43
Check whether the sum of all digits of the said number is odd or even!
Oddish
Original Number 4433
Check whether the sum of all digits of the said number is odd or even!
Evenish
Original Number 373
Check whether the sum of all digits of the said number is odd or even!
Oddish

Explanation:

Here is a breakdown of the above Python code:

• Function definition:
• The code defines a function named "oddish_evenish_num()" that checks whether the sum of digits of a given number (n) is odd or even.
• Sum of Digits:
• The sum(map(int, str(n))) expression converts the number to a string, maps each character to its integer equivalent, and calculates the sum of these integers.
• Oddish or Evenish Check:
• The function checks if the sum is odd using % 2 and returns 'Oddish' if true, otherwise 'Evenish'.
