如何随机 select 并使用 selenium webdriver（Python）单击元素？

Question

I have to randomly select an element from todo list app and click to delete it. Basically, every element has the same selector, just index changes (eg//*[@class="destroy"])[2]). I have code that generates random sentences and adds them to the app. Then I have to randomly select an element -> click on it to delete and here I got stuck. Random.choice selects a random number and actually, it works. But sometimes if it randomly selects [0] the test fails and test execution takes a lot of time and I believe there is a more professional way to make a random choice. Could you please advise other possible ways?

You can use random.randint(start, end) to specify a range of integers that can be randomly selected and pass that as the index.

random_element = f'//*[@class="destroy"])[{random.randint(startint,endint)}]'
