Python email validation using Boolean logic

Python Boolean Data Type: Exercise-8 with Solution

Write a Python program that implements a function to check if a given string is a valid email address format using boolean logic.

Sample Solution:

Code:

import re
def is_valid_email(email):
    # Regular expression pattern for valid email address format
    pattern = r'^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$'
    return re.match(pattern, email)

def main():
    try:
        email = input("Input an email address: ")
        
        if is_valid_email(email):
            print("Valid email address!")
        else:
            print("Invalid email address!")
    except Exception as e:
        print("An error occurred:", e)

if __name__ == "__main__":
    main()

Output:

Input an email address: abcd@example.com
Email address is valid.
Input an email address: _abc@example.com
Email address is valid.
Input an email address: $_abc@example.com
Email address is not valid.

In the exercise above the program prompts the user to enter an email address. In order to determine if the email address is valid, it uses the "is_valid_email()" function and a regular expression pattern. It prints the appropriate message based on the results.
