    for username use :

    driver.find_element_by_xpath("//input(@type='email')").click()
    driver.find_element_by_xpath("//input(@type='email')").send_keys( "username" )
    

    for password use :

    driver.find_element_by_xpath("//input(@type='password')").click()
    driver.find_element_by_xpath("//input(@type='password')").send_keys( "password" )

    This error message...

    selenium.common.exceptions.ElementNotVisibleException: Message: element not visible
    

    ...implies that the desired element was not visible within the HTML DOM while the WebDriver instance was trying to find it.


    ElementNotVisibleException

    ElementNotVisibleException is thrown when an element is present on the DOM Tree, but it is not visible, and so is not able to be interacted with.


    Reason

    One possitive take away from ElementNotVisibleException is the fact that the WebElement is present within the HTML and this exception is commonly encountered when trying to click() or read an attribute of an element that is hidden from view.


    Solution

    As ElementNotVisibleException ensures that the WebElement is present within the HTML so the solution ahead would be two folds as per the next steps as detailed below:

    • If you next step is to read any attribute of the desired element, then you need to induce WebDriverWait in-conjunction with expected_conditions clause set to visibility_of_element_located as follows:

      from selenium.webdriver.support.ui import WebDriverWait
      from selenium.webdriver.common.by import By
      from selenium.webdriver.support import expected_conditions as EC
      
      my_value = WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.XPATH, "element_xpath"))).get_attribute("innerHTML")
      
    • If you next step is to invoke click() on the desired element, then you need to induce WebDriverWait in-conjunction with expected_conditions clause set to element_to_be_clickable as follows:

      from selenium.webdriver.support.ui import WebDriverWait
      from selenium.webdriver.common.by import By
      from selenium.webdriver.support import expected_conditions as EC
      
      WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "element_xpath"))).click()
      

    This usecase

    The xpath you constructed as //h1[@class="sign-in-input"] doesn't match any node. We need to create unique xpath to locate the elements representing Email Address, Password and Sign In button inducing WebDriverWait. The below code block will help you to achieve the same:

    from selenium import webdriver
    from selenium.webdriver.chrome.options import Options
    from selenium.webdriver.support.ui import WebDriverWait
    from selenium.webdriver.common.by import By
    from selenium.webdriver.support import expected_conditions as EC
    
    options = Options()
    options.add_argument("start-maximized")
    options.add_argument("disable-infobars")
    options.add_argument("--disable-extensions")
    driver = webdriver.Chrome(chrome_options=options, executable_path="C:\\Utility\\BrowserDrivers\\chromedriver.exe")
    driver.get('https://www.TheGreatCoursesPlus.com/sign-in')
    WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//div[@id='modal']//input[@name='email']"))).send_keys("abc@abc.com")
    driver.find_element_by_xpath("//div[@id='modal']//input[@name='password']").send_keys("password")
    driver.find_element_by_xpath("//div[@id='modal']//button[@class='color-site sign-in-button']").click()

    There are two problems:

    • The first one is timing, it takes some time for the form to appear. You you can use explicit wait to solve it.
    • The second one is that the field id in <input> tag, not <h1> tag, and there are many fields that matches this xpath. I suggest you locate the form holding the fields and use it to locate each field

    For the timing issue you can use explicit wait

    from selenium.webdriver.common.by import By
    from selenium.webdriver.support.ui import WebDriverWait
    from selenium.webdriver.support import expected_conditions as EC
    
    driver = webdriver.Chrome()
    driver.get('https://www.TheGreatCoursesPlus.com/sign-in')
    form = WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.XPATH, '//div[@class="modal-body"]//form')))
    
    form.find_element_by_name('email').send_keys(email)
    form.find_element_by_name('password').send_keys(password)
    form.find_element_by_name('sign-in-button').click()
