This chapter aims to introduce the reader to the construction, prior mod- elling, estimation and evaluation of mixture distributions in a Bayesian paradigm. We will show that mixture distributions provide a flexible, para- metric framework for stati
这篇文章主要介绍了通过实例了解Python str()和repr()的区别,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
区别
其实用处就是最大的区别了:str()主要用来为终端用户输出一些信息,而repr()主要用来调试;同时后者的目标是为了消除一些歧义(例如浮点数的精度问题),前者主要为了可读。
使用
In [12]: s = 'abc'
In [13]: print(str(s))
abc
In [14]: print(2.0/11
