我们在pandas2.0中引入了支持PyArrow的DataFrame,并从那时起不断改进集成,以实现与pandas API的无缝集成。pandas为某些dtypes提供了访问器来实现专门的操作,比如字符串访问器,它提供了许多字符串方法。从历史上看,list和structs是以NumPy对象dtype表示的,这使得处理它们相当麻烦。现在,Arrow dtype后端可以为列表和结构体...
向量计算是Pandas和NumPy的核心,它对整个数组而不是单个标量执行数学运算。最棒的是Pandas已经拥有一套广泛的向量化函数,无须重新设计新的库。 Python中的所有算术运算符(+,-,*,/,**)在Pandas系列或数据帧上使用时都以向量化的方式工作。此外,你在Pandas或NumPy中看到的任何其他数学函数都已经向量化了。 为了看到速...
