Need to select an IFrame with selenium python

Question

I want to select an iframe and I am not able to do it now. Below is the HTML where I want to make it work:

<iframe id="upload_file_frame" width="100%" height="465px" frameborder="0" framemargin="0" name="upload_file_frame" src="/blah/import/">
<html>
    <body>
        <div class="import_devices">
            <div class="import_type">
                <a class="secondary_button" href="/blah/blah/?source=blah">
                    <div class="import_choice_image">
                        <img alt="blah" src="/public/images/blah/import/blah.png">
                    </div>
                    <div class="import_choice_text">Blah Blah</div>
                </a>
            </div>
        </div>
    </body>
</html>

My python code for finding the iframe is this:

    @timed(650)
def test_pedometer(self):
    sel = self.selenium
    ...
    time.sleep(10)
    for i in range(5):
        try:
            if sel.select_frame("css=#upload_file_frame"): break
        except: pass
        time.sleep(10)
    else: self.fail("Cannot find upload_file_frame, the iframe for the device upload image buttons")

At times this code works, but something si wrong and Selenium just fails most times. Not sure if the issue is because of some race condition or something? Can someone lead me in the right path?

Well for me, something like this worked. I've done inserting data within an iframe:

self.driver = webdriver.Firefox()

## Give time for iframe to load ##
time.sleep(3)

## You have to switch to the iframe like so: ##
driver.switch_to_frame(driver.find_element_by_tag_name("iframe"))

## Insert text via xpath ##
elem = driver.find_element_by_xpath("/html/body/p")
elem.send_keys("Lorem Ipsum")

## Switch back to the "default content" (that is, out of the iframes) ##
driver.switch_to_default_content()
