    • driver.find_element_by_xpath("//xpath//of//element") XPATH help
    • driver.find_element_by_name("name_of_element")
    • driver.find_element_by_id("id_of_element")
    • driver.find_element_by_partial_link_text("element_link_text")
    • driver.find_element_by_class_name("class_name_of_element")
    • driver.find_element_by_tag_name("tag_name_of_element")
  • Finds a list of elements:

  • click function:

    • driver.find_element_by_method.click()
  • send_keys function:

    • driver.find_element_by_method.send_keys("text") sends the String "text" to the element found.
    • driver.find_element_by_method.send_keys(KeyCode.UP) sends the KeyCode for the up arrow key to the element found.
