Python summary

The material for learning Python on the Internet is just overwhelming, mainly in English. So, what is the reason I am posting a set of articles called Python summary? Because I think they are useful for creating an own mindmap about Python and for brushing up quickly. Moreover, thereby I improve my English, and the articles should be useful to me if I gave lessons of this programming language.
