以windows版本举例：
1、首先去Pycharm官网，或者直接输入网址：http://www.jetbrains.com/pycharm/download/#section=windows，下载PyCharm安装包，根据自己电脑的操作系统进行选择，对于windows系统选择下图的框框所包含的安装包。
2,双击下载的安装包，进行安装，然后会弹出界面：

勾选Create Associations是否关联文件，选择以后打开.py文件就会用PyCharm打开。
5，点击Next，进入下图（默认安装即可）：
6，耐心的等待两分钟左右，如下图：
7，之后就会得到下面的安装完成的界面：
8，选择Accept，进入下一步：
9，进入激活界面，选择第二个License server，如下图所示：
