The dynamicness of languages like Python make it relatively easy to do so. For example, it's difficult in Java to mock an http request if you can't inject a `HttpRequestor` (or so) to the object you're testing. In Python, it is common practice to patch objects, which means that even though the code calls `requests.get()`, the call will actually be patched through to a mock. (in the Java world, this is possible with e.g. PowerMock, but generally frowned upon)
