1.12 Lab: Check Login Credentials (classes) Complete the Login class implementation. For the class method check credentials(), you will need to accept two arguments - login and passwd. Do not forget about the self argument. This class method will set two local variables simlogin = "Test' and simpass = "test1234". These variables will simulate the correct login and password for the credential check process. The method will receive the login and password from the user and check it with Test and test1234. If the user sent the correct credentials output: Successful login! If the user sent the correct login name but the wrong password output: Login name is correct, incorrect password! If the user sent an incorrect login name but the correct password output: Login name is incorrect, password accepted! If the user sent both incorrect login name and password output: Unsuccessful login attempt! The class method will return a boolean success variable as True if the login was successful. " Using if _name_ == "main_ to control the flow of your code, add a loop that will stop the process if the user attempts more than 5 login attempts. Ex: If the input is: Testit test And this is their first incorrect attempt. The output is: Unsuccessful login attempt! Try again - you have 4 attempts left! If the input is: Test test1234 The output is: Successful login!

OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Question
Please revise this code so that the outputs are correct.
Current it’s flagging a syntax error. See screen shot. Also view the lab ( 2nd ) screen shot.
Please use both inputs to produce both out outputs.
1st input:
Testit
test
1st output:
Unsuccessful login attempt!
Try again – you have four times left!
2nd input:
Test
Test1234
Second output:
Successful login!
Current code needs amended:
 #class Login
class Login:
#__init__
def __init__(self):
#initializing login_name as none
self.login_name = 'none'
#initializing login_password as none
self.login_password = 'none'
#check_credentials()
def check_credentials(self, user_login, user_passwd):
#initializing simlogin as 'Test'
simlogin = 'Test'
#initializing simpass as 'Test'
simpass = 'test1234'
#if user sent the correct credentials
