Selenium twitter unable to take username and password

Question

The following code is a segment of my program where I am trying to get followers of the screen_names given in excel file. Earlier my code was working fine, but now it gets stuck every time after loading twitter page on chrome. It does not enter username and password in browser. Please guide me on what could be wrong in the following code.

    *driver = webdriver.Chrome('C:/name/sport/chromedriver')
        driver.get("https://twitter.com/download?logged_out=1&lang=en")
        time.sleep(6) 
        driver.find_element_by_xpath("//*[@id='signin-link']").click()
        time.sleep(3)
        pagecount=driver.find_element_by_xpath("//*[@id='signin-email']").send_keys('mygmail')
        pagecount=driver.find_element_by_xpath("//*[@id='signin-password']").send_keys('mypassword')
        time.sleep(3)
        driver.find_element_by_xpath("//*[@id='signin-dropdown']/div[3]/form/input[1]").click()*

     22 time.sleep(3)

Answer 1

I look at Login form on https://twitter.com/download?logged_out=1&lang=en page, and I see no element with @id='signin-email' or @id='signin-password'. Instead I see login element as

<input type="text" class="text-input email-input js-signin-email" name="session[username_or_email]" autocomplete="username" placeholder="Phone, email or username">

and password as

<input type="password" class="text-input" name="session[password]" placeholder="Password" autocomplete="current-password">

So it means your xpath is wrong. Try

 pagecount=driver.find_element_by_xpath("//input[contains(@name,'username')]").send_keys('mygmail')
 pagecount=driver.find_element_by_xpath("//input[contains(@name,'password')]").send_keys('mypassword')

Also in the exception dump I believe you forgot to replace your real username/password, so you may want to change your password.
