Button animation is not working in a branch

it is simply ugly to compare a boolean variable to True or False like you do. Don't do it, follow @metullburr's advise.
This way you will also avoid stupid mistakes like comparing condition to some global? variable true. I say global variable, but it well may be in the tweepy code missing in the example. Because otherwise the interpreter will raise NameError.
If you didn't get it so far - it is True, not true
