Python with Webdriver - launch Firefox and Chrome browser

def setUp_and_login(browser):
        '''
        Supported browsers are: firefox; chrome
        '''
        #
        if browser == 'firefox':
            driver = webdriver.Firefox()
        elif browser == 'chrome':
            driver = webdriver.Chrome('Location of Chromedriver utility')
        else:
            print('')
            print('Browser not recognized, exiting...')
            print('')
            exit()

Purpose of self in Python

from selenium import webdriver
#
Class MyClass:
    def function(self):
        self.driver = webdriver.Firefox()

What is the purpose of SELF here:
"
self is an object reference to the object itself, therefore, they are same. Python methods are not called in the context of the object itself. self in Python may be used to deal with custom object models or something.
"

"
The self variable refers to the object itself.
