Software development mainly considerate two points that are an emphasis on process and the quality of the software and process itself. Well, when you define your functions or classes in such a way that they’re focused and responsible for a single functionality, your code becomes a lot easier to understand, maintain, and modify. This tweet by @phillip_webb sarcastically summarizes how we’re going a bit overboard with micro-services. Every software engineer has his or her own set of “fundamentals” that they will pass on – fundamentals that even as technology changes, are still appropriate for everyday building. Apply Fit for Purpose. 3: To manage product quality, the developers must measure quality. Don’t stop learning now. Some of these principles are Python-specific, but most are not. We use those fancy language features that no one knows about and feel proud. Some of you, myself included, may be surprised to hear that there’s more to the SDLC than just waterfall, agile, and DevOps. • We create endless micro-services for every simple thing. But if you have a single function that does too many things then you wouldn’t be able to use it if you only need a fraction of the functionality implemented by the function. Many of these principles relate to testing practices and ideals. The PMs collect requirements and track the progress of the project. Operational 2. Any software should be judged by what it offers and what are the methods which help you to use it. Another way of putting it is this: there are many ways to fail at developing high quality software and only a few ways to succeed. You can’t replace an object of the Bird class with an object of the Penguin class. To fix this, you could create another abstraction which captures the flying capability of a Bird -.
