python learning curve

PHP has been learning for a while, has a certain understanding of the grammar of Php/mysql itself, and has written two very small projects. Every day there is a lot of progress between the senses. Now I feel a lot of days no progress, but do not know how to continue to study, do not know how you phper that year how to learn? A few days ago tried to look at the thinkphp framework of the document, do not understand a lot of places, too many terms. Does

Below is my learning curve: Let me explain this figure:The first is the initial stage (one day, that is, the Foundation), and the second is the tool used for a learning point (that is, our weapon and sword ), the third is the advanced stage (double day, I do not know the maximum number of double days :)).
