But, unlike the first example, Python has a solution to this already:@functools.singledispatch. This is a decorator which transforms a function into a single-dispatch generic function. You then register other functions against it, specifying a type of object (that is, a class name). When the...
Understanding the scope and purpose of writing test cases is crucial. In the past, assumptions about how a test case should work led to challenges. Learning from experience, it became clear that having a solid grasp of the Software Requirement Specification (SRS) document is essential. Refraining...

A: async program is IO bound. A: A lot of very expensive people have optimised the snot out of python asyncio over years. It'll always be slower in the fixed overhead sense than C++, but in terms of scalability and corner case handling it ought to be close to optimal. ...
However, the project involves no third-party libraries, esoteric Python-specific features, or Python-dependent tooling. As such, you're free to implement the project in any programming language that you wish. Writing a compiler can also be a challenging way to learn a new programming language ...

Flyweight design pattern The Flyweight design pattern works by sharing common parts of the state among multiple objects instead of keeping all data in each object, significantly reducing the overall memory footprint. Consider a class representing graphical circles in a drawing application where each cir...

Today I'm starting a new series of articles about a topic that does not get a lot of coverage: how to write Python unit tests. Unlike other testing tutorials, I'm going to focus on testing techniques more than on the testing tools themselves. The idea is that in each part of this ...
