Step 1: Store default username and password

We are going to store username and password in a variable. Here I'm using mrperfect as username and perfectbro as password.

username = 'mrperfect'
password = 'perfectbro'{codeBox}

Step 2: Ask user for username and password

To ask or get input from user, we use input() function. This is a built-in python function. And we also have to store it in a variable. 

inputuser = input('[*] Enter username: ')
inputpass = input('[*] Enter password: '){codeBox}

Step 3: Match those credentials

We can use IF-ELSE statement to match those and do action if not matched. Since we want to exit the script if not matched, so we will use only IF statement. and since there is 2 conditions and 1 Logical operator, we will put conditions in a bracket.

if not (username==inputuser and password==inputpass):
    print('Incorrect username or password!\nPlease try again.')
    exit(){codeBox}

here exit() is a python built-in function. This function exit's the program.

Step 4: Put your main code after that

Since this is a tutorial so my main function is printing a text.

print('This is main function'){codeBox}

Full Code

username = 'mrperfect'
password = 'perfectbro'
inputuser = input('[*] Enter username: ')
inputpass = input('[*] Enter password: ')
if not (username==inputuser and password==inputpass):
    print('Incorrect username or password!\nPlease try again.')
    exit()

print('This is main function'){codeBox}
