download:Python Flask Quick start and advanced

Those of you who have mastered the basic syntax of Python know that the next step is to learn the Python framework, but what framework to choose and how to get through the “lag” period quickly are always difficult problems. We suggest that Flask can be used for transition and initiation. The “light” characteristic of Flask itself makes your learning less “heavy”. After mastering the core knowledge, you will be able to develop and gain a sense of achievement, which will make learning more motivated. FLask’s ability to “quickly” develop various types of applications is very well accepted in the Python Web space

Suitable for people who know the basic syntax of Python but don’t know what to do next students who are new to Python Web development
