2.2 Python Environment and modules

One is installed Python Computers in the environment ,Python The environment requires the following modules to be installed .

Dry goods mainly include ：

① 200 Multiple copies Python e-book （ And classic books ） Should have

② Python Standard library information （ The most complete Chinese version ）

③ Project source code （ Forty or fifty interesting and reliable hand training projects and source code ）

④ Python Basic introduction 、 Reptiles 、 Network development 、 Big data analysis video （ Suitable for Xiaobai to learn ）

⑤ Python Learning Roadmap （ Farewell to bad learning ）
