无法在Python中使用Selenium从下拉菜单中通过xpath选择元素

Question

I'm having a hard time trying to select an element from a dropdown menu with Selenium.

Inspecting the page it looks like this:

<select id="numbers" name="numbers" style="display: inline-block;">
<option value="all">all numbers</option>
<option value="c4ca4238a0b923820dcc509a6f75849b">One</option>
<option value="c81e728d9d4c2f636f067f89cc14862c">Two</option>
<option value="34173cb38f07f89ddbebc2ac9128303f">Three</option>
</select>

The code I'm using is:

element = WebDriverWait(driver, 20).until(
EC.element_to_be_clickable((By.XPATH, '//*[@id="numbers"]/option[3]'))
)

element.click();

But I'm receiving the error:

  EC.element_to_be_clickable((By.XPATH, '//*[@id="numbers"]/option[3]'))
  File "/Library/Python/2.7/site-packages/selenium/webdriver/support/wait.py", line 80, in until
    raise TimeoutException(message, screen, stacktrace)

For what I'm able to understand it's failing to locate the xpath, even if i double-checked copy/pasting it from Chrome.

What am I missing? Thank you for your help.

Answer 1

As, you have to select option from Select control, it is better to use Select class as shown below:

select = Select(driver.find_element_by_id("numbers"))
select.select_by_visible_text("Two")

Let me know, whether above code works for you.

Answer 2

I think first you need to click on that drop-down menu, than options will get displayed.

element = WebDriverWait(driver, 20).until(
EC.element_to_be_clickable((By.XPATH, '//*[@id="numbers"]')))
element.click();

and than perform click on //option[3]
