Python Conditional: Exercise - 31 with Solution
Write a Python program to calculate a dog's age in dog years.
Note: For the first two years, a dog year is equal to 10.5 human years. After that, each dog year equals 4 human years.
# Request input from the user to provide a dog's age in human years and convert it to an integer h_age = int(input("Input a dog's age in human years: ")) # Check if the entered age is less than zero; if true, display an error message and exit the program if h_age < 0: print("Age must be a positive number.") exit() # If the entered age is 2 years or less, calculate the dog's age in dog's years using the formula 10.5 times the human years elif h_age <= 2: d_age = h_age * 10.5 # For ages greater than 2, calculate the dog's age in dog's years using the formula 21 plus 4 times the remaining human years after 2 else: d_age = 21 + (h_age - 2) * 4 # Display the calculated dog's age in dog's years print("The dog's age in dog's years is", d_age)
Input a dog's age in human years: 12 The dog's age in dog's years is 61
