Python Code:
#License: https://bit.ly/3oLErEI
# Define a function named 'test' that takes an integer 'n' as input
def test(n):
# Check if any digit in the number is odd
if any(int(c) % 2 for c in str(n)):
# Initialize a variable 'prod' to store the product of odd digits
prod = 1
# Iterate over each digit in the number
for c in str(n):
# If the digit is odd, multiply it with the current product
if int(c) % 2 == 1:
prod *= int(c)
# Return the final product of odd digits
return prod
# Return 0 if there are no odd digits in the number
return 0
# Assign a specific integer 'n' to the variable
n = 123456789
# Print a message indicating the operation to be performed
print("Original Number:", n)
# Print a message indicating the operation to be performed
print("Product of the odd digits in the said number, or 0 if there aren't any:")
# Print the result of the test function applied to 'n'
print(test(n))
# Assign another specific integer 'n' to the variable
n = 2468
# Print a message indicating the operation to be performed
print("\nOriginal Number:", n)
# Print a message indicating the operation to be performed
print("Product of the odd digits in the said number, or 0 if there aren't any:")
# Print the result of the test function applied to 'n'
print(test(n))
# Assign another specific integer 'n' to the variable
n = 13579
# Print a message indicating the operation to be performed
print("\nOriginal Number:", n)
# Print a message indicating the operation to be performed
print("Product of the odd digits in the said number, or 0 if there aren't any:")
# Print the result of the test function applied to 'n'
print(test(n))
Sample Output:
Original Number: 123456789 Product of the odd digits in the said number, or 0 if there aren't any 945 Original Number: 2468 Product of the odd digits in the said number, or 0 if there aren't any 0 Original Number: 13579 Product of the odd digits in the said number, or 0 if there aren't any 945
