安装IDE
1.PyCharm是一个多功能的集成开发环境，只需要在pycharm中创建python file就运行python，并且pycharm内置完备的功能，自动补全，代码提示，调试运行，代码的编辑、改正、优化，还能自动结合Git进行代码版本控制，当需要做一个大型项目时，用带有项目管理功能的PyCharm最方便。
2.PyCharm的安装也十分简单
直接进官网PyCharm: Python IDE for Professional Developers by JetBrains，点download
启动PyCharm，接下来有一个激活码的问题，在网上看到了一个非常神奇的操作：
选择activation code激活，复制以下code粘贴到activation code ,然后点Active激活即可。
最后一步是否安装Vim，Markdown，Bash等编辑器插件，建议根据个人代码习惯安排，R语言插件可以装一下，也可以什么不安，干净又快。
