Example of touch event with webdriver python?

I have seen about 100 touch event examples for the Java webdriver online, but not a single one for python. Would someone be so kind as to post one here, so it saves people many hours of search?Here is my attempt to do a basic double_tap on an element in an android simulator in order to zoom in on it. Much thanks

EDIT: Thanks to Julian's help I was able to figure out the missing link: for some reason, the touch actions require an extra .perform() at the end. Below you will find a bunch of touch events in action--and the code is cleaner. Enjoy!

import unittest, timefrom selenium import webdriverprint "Here are our available touch actions (ignore the ones that look like __xx__): ", dir(webdriver.TouchActions)#print dir(webdriver)class Test(unittest.TestCase):    def setUp(self):        self.driver = webdriver.Remote(command_executor='http://localhost:8080/wd/hub',  desired_capabilities=webdriver.DesiredCapabilities.ANDROID)        self.touch =webdriver.TouchActions(self.driver)        #self.driver = TouchActions(self.driver)        #self.driver = webdriver.Firefox()        self.driver.implicitly_wait(30)    def testHotmail(self):        self.driver.get("http://www.hotmail.com")        elem=self.driver.find_element_by_css_selector("input[name='login']")        #tap command        self.touch.tap(elem).perform()        time.sleep(2)        elem.send_keys("hello world")        time.sleep(2)        #double tap        self.touch.double_tap(elem).perform()        time.sleep(2)        #testing that regular webdriver commands still work        print self.driver.find_element_by_partial_link_text("Can't access").text        elem= self.driver.find_element_by_css_selector("input[type='submit']")        self.touch.tap(elem).perform()        time.sleep(3)    def tearDown(self):        time.sleep(3)        try:            self.driver.quit()        except Exception:            print(" TearDown Method: Browser seems already closed.")        passif __name__ == "__main__":    unittest.main()

Here is an original Java Example:

WebElement toFlick = driver.findElement(By.id("image"));// 400 pixels left at normal speedAction flick = getBuilder(driver).flick(toFlick, 0, -400, FlickAction.SPEED_NORMAL)        .build();flick.perform();WebElement secondImage = driver.findElement(“secondImage”);assertTrue(secondImage.isDisplayed());
