To secure your account, whether it be an email, online bank account or any other account, it is important that we use authentication. Use your programming expertise to create a program using user defined function named login that accepts userid and password as parameters (login(uid,pwd)) that displays a message "account blocked" in case of three wrong attempts. The login is successful if the user enters user ID as "ADMIN" and password as "StOrE@1". On successful login, display a message "login successful".

Here is a Python program using the

login

function to authenticate a user with three attempts:

# Define login function
def login(uid, pwd):
    # Initialize attempt counter
    attempts = 0
    
    while attempts < 3:
        # Increment attempts
        attempts += 1
        
        # Check if the provided credentials match the correct ones
        if uid == "ADMIN" and pwd == "StOrE@1":
            print("login successful")
            return
        
        # If credentials don't match, ask for them again
        print("Invalid credentials. Try again.")
        
        # Allow user to retry if attempts are less than 3
        if attempts < 3:
            uid = input("Enter user ID: ")
            pwd = input("Enter password: ")

# If three attempts are exhausted, block the account
    print("account blocked")

# Take user input for user ID and password
input_uid = input("Enter user ID: ")
input_pwd = input("Enter password: ")

# Call the login function with the provided inputs
login(input_uid, input_pwd)
