Question

Write a program in python that checks if an email is valid or not by checking if there is an ‘@’ and ‘.’ in the provided string. Declare 3 variables that include 3 different emails, pass these variables as an argument to a function, and the function should return whether the email is valid or not.
Example,
email1 = “hello.edu” à INVALID
email2 = “hello@sju.edu” à VALID
email3 = “my email address is: email@sju.edu” à VALID

Tip,
In order to check if a string contains a character, we can use in keyword in a conditional statement. See below:

>>> email = ‘hello@sju.edu’
>>> if "@" in email and "." in email: ... print(email, "valid")
>>> else:

print(email, "invalid")

Answer 1

def checkEmail(email):
    if "@" in email and "." in email:
        print(email, "valid")
    else:
        print(email, "invalid")

# Testing
email1 = "hello.edu"
email2 = "hello@sju.edu"
email3 = "my email address is: email@sju.edu"
checkEmail(email1)
checkEmail(email2)
checkEmail(email3)
