How do I write the function for Selenium to wait for a table with just a class identifier in Python? I'm having a devil of a time learning to use Selenium's Python webdriver functions.
I have made good experiences using:

time.sleep(seconds)
webdriver.Firefox.implicitly_wait(seconds)

The first one is pretty obvious - just wait a few seconds for some stuff.
For all my Selenium Scripts the sleep() with a few seconds (range from 1 to 3) works when I run them on my laptop, but on my Server the time to wait has a wider range, so I use implicitly_wait() too. I usually use implicitly_wait(30), which is really enough.

An implicit wait is to tell WebDriver to poll the DOM for a certain amount of time when trying to find an element or elements if they are not immediately available. The default setting is 0. Once set, the implicit wait is set for the life of the WebDriver object instance.
