Average Grade: 84.5 1. 2. 3. 4. 5. 6. 总结 通过上述代码示例,我们成功将一个Python类的实例列表转换为pandas的DataFrame。这一过程展示了如何提取对象的属性并重组成一个结构化的数据格式,为数据分析提供了便利。使用pandas的强大功能,可以进一步对数据进行各种复杂的操作,帮助我们从数据中获得有价值的
3.2 用pandas自带的函数.pivot_table()来统计船舱等级与平均票价的关系 看了3.1后发现,我们的需求很简单,但是代码实现起来并不是很简便,那么有没有什么Pandas自带的方法来简便的完成这类数据统计的操作呢?答案当然是肯定的啦,不然我怎么会又开了3.2. 吼吼 .pivot_table() : 相当于一个数据透视表。 也相当于统计...

我尝试在Python3.8和pandas 1.1.0上重现您的代码。我从第一个函数中得到了错误TypeError: dtype timedelta64[ns] cannot be converted to datetime64[ns]。我认为这个错误是不言而喻的:您不能通过调用to_datetime()将时间差转换为时间戳。时间增量在时间上没有要转换为戳的引用。话虽如此,我还是很惊讶你的代码...
