Python Selenium: Send_keys Failed to execute

I'd like to fill out a form with

driver.find_element_by_id("name").send_keys("Test")

But I get this error everytime I run the script:

Traceback (most recent call last):
  File "fill.py", line 22, in <module>
    driver.find_element_by_id("name").send_keys("Test")
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 351, in find_element_by_id

<input first_and_last="true" placeholder="name" class="string required" type="text" name="flname" id="name">

Note: I also get an error for searching for the name. If I search for Xpath it fills out the form very slow and I need it to be faster.

How can I solve this problem?

Solution

  • Use either of the locator Strategies :

    • css_selector :

      driver.find_element_by_css_selector("input.string.required#name").send_keys("Test")

    • xpath :

      driver.find_element_by_xpath("//input[@class='string required' and @id='name']").send_keys("Test")

    Update

    I have tried to lookout for a solution to both of the error messages you were facing and here are the relevant details :
