Two methods do same thing but, there is a small difference;
driver.close() is used to close the current browser that we are
running the test.
driver.quit() is used to close all the browser opened by Selenium
Webdriver.
# driver.close() closes one tab
# driver.quit() quits the session
# this closes all tabs but doesnt quit the session as a whole
alltabs = driver.window_handles
for i in range(len(alltabs)):
driver.switch_to.window(alltabs[i])
driver.close();sleep(1)
