>>>type(int)<class'type'>>>type(list)<class'type'> 从本质上讲,python的OOP机制主要依赖两个基础:1.函数的第一个参数;2.继承属性搜索。除此之外,python的OOP模型基本就是处理内置类型的函数。 OOP不仅是一门技术,更是一种经验。 因为OOP不是在所有场景下都优于POP(Procedure-Oriented Programmin) python...

Python语言采用严格的缩进来表示程序逻辑。也就是我们所说的Python程序间的包含与层次关系。一般代码不要求缩进,顶行编写且不留空白。在if、while、for、def、class等保留字所在完整语句后通过英文的“:”结尾并在之后行进行缩进,表明后续代码与紧邻无缩进语句的所属关系。
PyCM is a multi-class confusion matrix library written in Python that supports both input data vectors and direct matrix, and a proper tool for post-classification model evaluation that supports most classes and overall statistics parameters. PyCM is the swiss-army knife of confusion matrices, targe...
