How to Input Your Age in Python

Python, a popular high-level programming language, offers numerous features and capabilities for both beginners and experts. One basic yet fundamental aspect of any programming language is user input and output. In this article, we’ll discuss how to input your age in Python and then display it on the screen.

The process of getting user input in Python typically involves the input() function. This function pauses the execution of the program, allowing the user to type in a value. The input is then returned as a string. If you want to perform numerical operations on the input, you’ll need to convert it to an integer or a float using the int() or float() functions.

Here’s a simple Python program that prompts the user to enter their age and then displays it on the screen:

python# Prompt the user to enter their age
age_input = input("Please enter your age: ")

# Convert the input to an integer
try:
    age = int(age_input)
    if age < 0:
        raise ValueError("Age cannot be negative.")
except ValueError as e:
    print("Invalid input:", e)
else:
    # Display the age
    print("Your age is:", age)

In this program, we first use the input() function to prompt the user to enter their age. The input is stored in the age_input variable as a string.
Next, we use a try-except block to handle potential errors that might occur during the conversion process. We attempt to convert the input string to an integer using the int() function. If the conversion is successful, we store the resulting integer in the age variable. However, if the input cannot be converted to an integer (e.g., if it contains non-numeric characters or if it’s negative), a ValueError exception will be raised.
In the except block, we catch the ValueError exception and print an error message indicating that the input is invalid.
If the conversion is successful (i.e., no exception is raised), the program proceeds to the else block. Here, we use the print() function to display the user’s age on the screen.
By following this approach, you can easily input your age in Python and perform various operations or comparisons based on the input value. Remember to always validate user input to ensure that it’s in the expected format and range.
