http://docs.python.org/library/stdtypes.html#boolean-values 引用自doc: Boolean values are the two constant objects False and True. They are used to represent truth values (although other values can also be considered false or true). In numeric contexts (for example when used as the argument...
一个神奇的Python机器学习交互应用开放框架 向大家推荐一款机器学习用户交互工具开发框架——Streamlit,可以使机器学习工程师能更轻松地创建自定义应用程序已在他们的模型中与数据进行交互。 废话不多说,先来看看它有多神奇~ 这是用streamlit开发的Uber数据集交互式仪表板,运行这个Demo前需要先安装streamlit 代码语言:javas...

Python-GC 在 Python 中,大多数对象的生命周期都是通过对象的引用计数来管理的。这是最直观也是最简单的垃圾回收机制。但是他有执行效率的问题和一个致命的弱点循环引用。 很显然,像 PyIntObject、PyStringObject 这些对象是绝不可能产生循环引用的,因为它们内部不可能持
