For This Assignment You Must Use The Rules Above To Calculate the Age
For this assignment, you must use the rules above to calculate the age of a dog in human years given its weight and its actual age. Your program must do the following:
1. Display a welcome message with your name in it.
2. Prompt the user for the name of the dog.
3. Repeatedly prompt the user for the age of the dog until the user enters a value between 1 and 16.
4. Repeatedly prompt the user for the weight of their dog until the user enters a weight that is greater than zero.
5. Display the age of the dog using the name that the user entered in step 2.
6. Repeatedly ask the user if they want to calculate the age of another dog until the user answers Y or N.
7. If the user enters Y, go back to step 2.
8. If the user enters N, display a thank you message and exit the program. Any time the user enters invalid input, the program should display an error message before proceeding.

Dog Age to Human Years Calculator
Author: Your Name Here
Introduction
The purpose of this program is to calculate a dog's age in human years based on its actual age and weight, following predefined rules. This interactive console application guides the user through multiple input prompts, validates data, and performs calculations accordingly. It emphasizes user input validation, repeated prompts, and personalized output, demonstrating fundamental programming concepts such as loops, conditionals, and input validation.
Program Implementation
1. Welcome Message
Upon starting, the program displays a welcome message that includes the user's name, creating a personalized greeting. For instance, "Welcome to the Dog Age Calculator, designed by Your Name."
2. Input: Dog's Name
The program prompts the user to enter the dog's name, which will be used in subsequent outputs. This step personalizes the experience and makes the output more engaging.
3. Input Validation: Dog's Age
The program prompts the user for the dog's age and continues prompting until the user enters a valid age between 1 and 16. If invalid input occurs (non-numeric or out of range), an error message is displayed, and the prompt repeats.
4. Input Validation: Dog's Weight
The program prompts for the dog's weight, repeatedly asking until the user inputs a value greater than zero. Invalid inputs trigger error messages and re-prompts.
5. Calculating and Displaying Age in Human Years
Based on the provided age and weight, the program calculates the dog's age in human years according to predefined rules. The calculated age is then displayed, including the dog's name for clarity and personalization.
6. Repetition for Multiple Dogs
The program asks whether the user wants to calculate the age for another dog, expecting inputs 'Y' or 'N'. It validates this input, re-prompting if invalid. If 'Y', the program loops back to step 2; if 'N', it proceeds to exit.
7. Exit Message
On choosing not to continue, the program displays a thank-you message and terminates, ending the session respectfully.
Handling Invalid Inputs
Throughout the program, any invalid user inputs—such as non-numeric entries where numbers are expected, out-of-range values, or unexpected responses—trigger error messages that inform the user about the invalid input before prompting again. This ensures robust and user-friendly interaction, reducing errors and increasing usability.
Sample Implementation Code in Python
def main():
Display welcome message
print("Welcome to the Dog Age Calculator, designed by Your Name.")
while True:
Get dog's name
dog_name = input("Please enter the dog's name: ").strip()
if not dog_name:
print("Error: Dog's name cannot be empty. Please try again.")
continue
Get dog's age with validation
while True:
age_input = input("Enter the dog's age (1-16): ").strip()
if not age_input.isdigit():
print("Error: Invalid input. Please enter a numeric value.")
continue
age = int(age_input)
if 1
break
else:
print("Error: Age must be between 1 and 16. Please try again.")
Get dog's weight with validation
while True:
weight_input = input("Enter the dog's weight (greater than 0): ").strip()
try:
weight = float(weight_input)
if weight > 0:
break
else:
print("Error: Weight must be greater than zero. Please try again.")
except ValueError:
print("Error: Invalid input. Please enter a numeric value.")
Calculate dog's age in human years
human_age = calculate_human_age(age, weight)
print(f"{dog_name} is approximately {human_age} years old in human years.")
Ask user if they want to calculate another dog's age
while True:
response = input("Would you like to calculate another dog's age? (Y/N): ").strip().upper()
if response == 'Y':
break
elif response == 'N':
print("Thank you for using the Dog Age Calculator. Goodbye!")
return
else:
print("Error: Please respond with 'Y' or 'N'.")
def calculate_human_age(dog_age, dog_weight):
Placeholder for actual calculation rules based on weight and age
For demonstration, assume a simple rule
if dog_weight
return dog_age * 4
elif dog_weight
return dog_age * 5
else:
return dog_age * 6
if __name__ == "__main__":
main()
Conclusion
This program provides an interactive and validated approach to calculating a dog's age in human years. With clear prompts, error handling, and personalization, it ensures an engaging user experience while demonstrating core programming principles such as input validation, control structures, and functions.
