Selenium Python run test cases how do i log in once and use the same instance browser

Question

I am new learner on Selenium Python have created some Test Cases in different py file in Selenium Python. Each time a py file runs it opens the browser and navigates to the URL.

-Test (Package)
  -Test_Login.py
  -Test_Search.py
  -Test_Create.py

How to execute the Test_Search.py and Test_Create.py using same instance browser with logged in ?

-Test_Login.py

import unittest
from selenium import webdriver
import time

class Test_Login( unittest.TestCase ):

    @classmethod
    def setUpClass(cls):
        cls.driver = webdriver.Chrome( '../Driver/chromedriver.exe' )
        cls.driver.implicitly_wait( 10 )
        cls.driver.get( "url...etc" )

    def test_A_Login(self):
        ###login action ....etc

    @classmethod
    def tearDownClass(cls):
            cls.driver.quit()
        
if __name__ == '__main_':
    unittest.main()
    

-Test_Search.py

import unittest
from selenium import webdriver
import time

class Test_Search( unittest.TestCase ):

    @classmethod
    def setUpClass(cls):
        cls.driver = webdriver.Chrome( '../Driver/chromedriver.exe' )
        cls.driver.implicitly_wait( 10 )
        cls.driver.get( "url...etc" )

    def test_A_Search(self):
        ###Search testing ....etc

    @classmethod
    def tearDownClass(cls):
        cls.driver.quit()
        
if __name__ == '__main_':
    unittest.main()
