The def keyword is used with parenthesis to define and declare a function in python. We create a function for login to a system and we call it login .
So by using def keyword before the login function, we are able to define or declare the login function. Inside the login() function we create variables for username and password and since username and password are user generated, we use the python in-built input() function to assign values to these two variables, username and password.
Then we use the if-else conditional loop to control the login() function. If the username and password input by the user , matches with the specific values assigned, then the login is successful, and the we can break away from the loop by using break keyword in python. Else, the loop will show the user, an error message requesting the user to try again by entering the correct username and password. This loop continues using the keyword, continue
