title: Is there a python alternative to Ruby's VCR library?
body: <p>I'd like to use the awesome "record/playback" mechanism of <a href="https://github.com/myronmarston/vcr">Ruby's VCR library</a> or <a href="http://freeside.co/betamax/">Betamax for the JVM</a>. Is there a Python library that works the same way? If not, how do you test your REST  client calls without worrying about the test being slow and flaky?</p>
