一、Python所有方向的学习路线
Python所有方向路线就是把Python常用的技术点做整理,形成各个领域的知识点汇总,它的用处就在于,你可以按照上面的知识点去找对应的学习资源,保证自己学得较为全面。

工欲善其事必先利其器。学习Python常用的开发软件都在这里了,还有环境配置的教程,给大家节省了很多时间。

书籍的好处就在于权威和体系健全,刚开始学习的时候你可以只看视频或者听某个人讲课,但等你学完之后,你觉得你掌握了,这时候建议还是得去看一下书籍,看权威技术书籍也是每个程序员必经之路。

我们在看视频学习的时候,不能光动眼动脑不动手,比较科学的学习方法是在理解之后运用它们,这时候练手项目就很适合了。

光学理论是没用的,要学会跟着一起敲,要动手实操,才能将自己的所学运用到实际当中去,这时候可以搞点实战案例来学习。
