I've often found Python's context managers to be pretty useful. They make a nice interface that can handle starting and ending of temporary things for you, like opening and closing a file.

I'm a big fan of proper unit testing with mocking. So I'm pretty disappointed when we run across a unit that is not only not mocked properly, but results in real-world consequences outside the testing environment. One case we've run into couple of times now is tests that are making actual outbound HTTP requests to remote servers. Since clients don't necessarily like getting fake information posted to their servers every time you run tests, I figured this was a good time to get to the bottom of this.
