Python Exercise 1.2: Age Calculator
Create a Python program that asks for the user's birth year and calculates their current age.
Your program should:
- Ask the user for their Birth Year (integer).
- Get the Current Year (e.g., 2025).
- Calculate the Age by subtracting the birth year from the current year.
- Print the result in a friendly sentence.
Bonus Challenge: Handle the case where they haven't had their birthday yet this year (requires asking for birth month/day). For this basic exercise, we will assume the birthday has passed.
Sample Interaction:
Input
Output
2000
Enter your birth year: 2000
--------------------
Current Year: 2025
You are approximately 25 years old.
Solution
Here is how you can solve this using the datetime module to get the real current year automatically.
import datetime
# 1. Get User Input
birth_year = int(input("Enter your birth year: "))
# 2. Get Current Year
# date.today().year gives us the current year (e.g., 2025)
current_year = datetime.date.today().year
# 3. Calculate Age
age = current_year - birth_year
# 4. Print Output
print("-" * 20)
print(f"Current Year: {current_year}")
print(f"You are approximately {age} years old.")
Key Concepts:
int()converts the input string to a number so we can do math.import datetimeallows us to work with real dates.datetime.date.today().yearfetches the system's current year dynamically.
