你当然也可以在代码中使⽤ from numpy import * ,但不建议这么做。 numpy 的命名空间很⼤,包含许多函数,其中⼀些的名字与Python的内置函 数重名(⽐如min和max)。 darray是⼀个通⽤的同构数据多维容器,也就是说,其中的所有元素必须是相同类型的。每个数组都有⼀个shape(⼀个表示各维度⼤⼩的...
the `dtype` will be takenfrom the data.2. Otherwise, pandas will attempt to infer the `dtype`from the data.Note that when `data` is a NumPy array, ``data.dtype`` is*not* used for inferring the array type. This is becauseNumPy cannot represent all the types of data that can beheld...
