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。pycharm现在在官网[https://www.jetbrains.com/pycharm/download/#section=windows]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。 PyCharm 是我用过的python编辑器中,比较顺手的一个。而且可以跨平台,在macos和windows下面都可以用,这点比较好。是python现在最好用的编辑器,没有之一。 安装包 PyCharm 笔者使用PyCharm2018.3.2,请根据机器是64位还是32位来选择对应的PyCharm版本。(相信绝大部分人都可以很从容的来查看自己机器的位数
