the issue is actually that the cols must be list rather than a pandas column object. Column object should be supported though in the future, that'd be a useful addition. I'm leaving the issue open to remind myself of adding support for columns. ...
Everything read by the CSV parser is a string. We do some checking for whether those strings should be converted to a specialized type (numeric, datetime-like). Pandas considersIndex([True, False])to be object dtype, which is also used for strings, so it's skipped. ...

接下来作者将对其中比较重要常用的四个扩展包(Numpy、Pandas、Matplotlib、Sklearn)进行简单的介绍,这些包更多的实例应用将在后面章节实例中讲解。 注意:本文数据分析部分推荐读者使用Anaconda或PyCharm中的集成环境,它已经集成安装了所使用的数据分析扩展包,安装后可以直接调用。 三.Numpy NumPy(Nume...
