> **Real\_Author** : Luo Hao > > **Note** : Since the project was launched to the 8w+ star, I have been receiving feedback that the basic part (the content of the first 15 days) is difficult for novices, and it is recommended to have a supporting video for explanation. Recently, I recreated a project called [“Python-Core-50-Courses”](https://github.com/jackfrued/Python-Core-50-Courses) from the basic part of the content **. This part of the content was rewritten in a simpler** and **more popular way and accompanied by a video explanation**. Beginners can pay attention to this new project. If domestic users are slow to access GitHub, they can also pay attention to the [“Learn Python from scratch”](https://zhuanlan.zhihu.com/c_1216656665569013760) column on my Zhihu [Python-Jack](https://www.zhihu.com/people/jackfrued) . The column will continue to be updated, and the content of “data analysis” that everyone is looking forward to will also be coming soon Online, **welcome everyone to pay attention to my columns, articles and answers in Zhihu**. > > The creation is not easy. Thank you for your rewards and support. The money will basically not be used to buy coffee. Instead, it will be donated to people in need through platforms such as Tencent Charity, Meituan Charity, and Didi Chuan ( [click to](https://github.com/jackfrued/Python-100-Days/blob/master/%E6%9B%B4%E6%96%B0%E6%97%A5%E5%BF%97.md) learn about donations). Those who need to join the QQ exchange group can scan the QR code below. The exchange group will provide you with **learning resources** and **answers to questions** , and will continue to bring you **free online Python experience courses and industry open courses** , so stay tuned.

Software process model - Classic process model (waterfall model) - Feasibility analysis (whether the research is done or not), and output the “feasibility analysis report”. - Requirement analysis (study what to do), output “requirements specification” and product interface prototype diagram. - Outline design and detailed design, output conceptual model diagram (ER diagram), physical model diagram, class diagram, sequence diagram, etc. - Coding/testing. - Go online/maintenance.The biggest disadvantage of the waterfall model is that it cannot embrace changes in requirements. The product can only be seen after the entire process is over, and the team morale is low. - Agile Development (Scrum)-Product Owner, Scrum Master, R&D Staff-Sprint - Product Backlog (user story, product prototype). - Planning meetings (evaluation and budgeting). - Daily development (stand-up meeting, Pomodoro Technique, pair programming, test first, code refactoring…). - Fix bugs (problem description, reproduction steps, testers, designees). - release version. - Review meeting (Showcase, users need to participate). - Retrospective meeting (a summary of the current iteration cycle). > Supplement: Manifesto for Agile Software Development > > ``` > * **Individuals and interactions are** higher than processes and tools > * **Working software is** higher than detailed documentation > * **Customer cooperation is** higher than contract negotiation > * **Responding to changes is** better than following a plan > > ``` [![](https://github.com/jackfrued/Python-100-Days/raw/master/res/agile-scrum-sprint-cycle.png)](https://github.com/jackfrued/Python-100-Days/blob/master/res/agile-scrum-sprint-cycle.png) > Roles: product owner (the person who decides what to do and can approve the demand), team leader (solve various problems, focus on how to work better, shield the external influence on the development team), development team (project executive, Specifically refers to developers and testers). > Preparation work: business case and capital, contract, vision, initial product requirements, initial release plan, shareholding, and team formation. > Agile teams usually have 8-10 people. > Estimation of workload: Quantify the development tasks, including prototype, logo design, UI design, front-end development, etc., try to break down each work to the minimum amount of tasks, the minimum task amount standard is that the working time cannot exceed two days, and then estimate the overall project time . Post each task on the Kanban board, which is divided into three parts: to do (to be completed), in progress (in progress) and done (completed). 1.

Requirements understanding, module division and task allocation - Need understanding: brainstorming and competitive product analysis. - Module division: draw a mind map (XMind), each module is a branch node, and each specific function is a leaf node (expressed in verbs). It is necessary to ensure that each leaf node cannot regenerate a new node, and determine each leaf The importance, priority and workload of the node. - Task assignment: The project leader assigns tasks to each team member according to the above indicators.[![](https://github.com/jackfrued/Python-100-Days/raw/master/res/requirements_by_xmind.png)](https://github.com/jackfrued/Python-100-Days/blob/master/res/requirements_by_xmind.png) 1.

Use of uWSGI/Gunicorn and Nginx - Comparison of Gunicorn and uWSGI - For simple applications that do not require a lot of customization, Gunicorn is a good choice. The learning curve of uWSGI is much steeper than that of Gunicorn. Gunicorn’s default parameters can already be adapted to most applications. - uWSGI supports heterogeneous deployment. - Since Nginx itself supports uWSGI, Nginx and uWSGI are generally bundled and deployed online, and uWSGI is a fully functional and highly customized WSGI middleware. - In terms of performance, Gunicorn and uWSGI are actually comparable. 1. Use virtualization technology (Docker) to deploy test and production environments ##### Performance Testing 1. Use of AB 2. Use of SQLslap 3. Use of sysbench ##### automated test 1.
