We can tell the type of the variable using this and not initialize it with any value. The new PEP 526 introduced the syntax for annotating variables of the required type (including class variables and instance variables) without comments. ...

The list of metrics to be calculated can be changed by editing the return value of get_metrics_names(). Cross validation is now used by default for forecasting models created via code generation. Converting decimal type y-test into float to allow for metrics computation to proceed w...
这份文档为主Python发行版中标准库的Python代码提供了编码规范。请参阅相关的信息性PEP,该PEP描述了Python C实现中的C代码的样式指南。 这份文档和PEP 257(文档字符串规范)改编自Guido的原始Python样式指南文章,并加入了Barry样式指南的一些内容[2]。 随着额外的约定的发现和语言本身的变化使过去的约定变得过时,这个样...
