The built-in namespaces are always available in the Python interpreter; for example, if we want to use the sum() function, we don't have to import it. See the code below, which finds the sum of numbers in a list using the built-in sum() function. 1 >>> sum_numbers = sum([3,...
As we mentioned in our article Python vs. Java, Python is considered a "very powerful and clear object-oriented programming language". Another great plus is that users can download and use it for free. Since it is available under the GNU General Public License (GPL), it can be freely red...
All in all, this is an unsalvageable mess. Why can’t Python pick one tool? What does the competition do? We’ll look at this in a minute. But first, let’s talk about the elephant in the room: Python virtual environments.Does Python really need virtual environments? Python relies on...

We use three functions (to neatly separate concerns). stripGLMModel()is fromTrimming the fat from glm models in Rand does the ugly work of stomping out fields we are not using and re-writing environments of functions. This is exactly the work we have to do because theglm()function itself...
when a message is delivered to a consumer the consumernotifies the broker, either automatically or as soon as the application developer chooses to do so. When message acknowledgements are in use, a broker will only completely remove a message from a queue when it receives a notification for tha...
