PyCharm 使用教程
Jetbrains 家族和 Pycharm 版本划分：
pycharm 是 Jetbrains 家族中的一个明星产品，Jetbrains开发了许多好用的编辑器
包括：
Java 编辑器（IntelliJ IDEA）
JavaScript 编辑器（WebStorm）
PHP 编辑器（PHPStorm）
Ruby 编辑器（RubyMine）
C 和 C++ 编辑器（CLion）
.Net 编辑器（Rider）
iOS/macOS 编辑器（AppCode）等等。
pycharm 现在在官网是分为两个版本，第一个版本是「Professional(专业版本)」，这个版本功能更加强大，主要是为 Python 和 web 开发者而准备，是需要付费的。第二个版本是「社区版」，一个专业版的阉割版，比较轻量级，主要是为 Python 和数据专家而准备的。一般我们做开发，下载专业版本比较合适。
更换 Python 解释器：
在File->Setting->Projec: xxx 下找到 Project Interpreter。然后修改为你需要的 Python 解释器。注意这个地方一定要注意的是：在选择 Python 解释器的时候，一定要选择到 python.exe 这个文件，而不是 python 的安装文件夹。
祝大家成功激活pycharm~~~
