title: Python selenium switch to default content not working
body: <p>I've been trying for ages to switch out of an iframe in selenium for python, I've tried every switch_to there is, but to no avail. The error I'm getting is when I switch to the second iframe <em>("iframe")[1]</em>. I get an index error because for some reason it doesn't switch out of the first iframe. This is the code I have at the moment. </p>
  
  <pre><code>main_win = driver.current_window_handle
  driver.switch_to.frame(driver.find_elements_by_tag_name("iframe")[0])
  WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID ,"btn1"))).click()
  
  sleep(2)
  
  # This is some of the different things I have tried, of course I've tried them separately. I've tried every variation there is of every switch_to* and it hasn't worked at all.
  driver.switch_to.parent_frame
  driver.switch_to.default_content 
  driver.switch_to.(main_win)
  
  sleep(2)
  driver.switch_to.frame(driver.find_elements_by_tag_name("iframe")[1])
  WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID ,"btn2"))).click()
  </code></pre>
  
  <p>When debugging I tried commenting out everything but the last 2 lines, and then it worked. It switched to the second iframe and clicked "btn3" with no problems. It's clear that the error lies in the switching out of the the first iframe. Thank you very much for helping, this is very frustrating</p>
