Flask is one of the most used Python frameworks in the world. Its popularity is comparable to Django.
What are its special characteristics?
Flask has the advantage of being very light and very little directive. Which means that leaves the choice to the user to build and use the tools that compose it.
It is the ideal choice for small and medium sized projects.
For this reason, we will use it in your project, if your main goal is to create a mini website or interesting APIs to facilitate the distribution and collection of information.
