We typically use Numpy arrays quite a bit for data science, machine learning, and scientific computing. When working with numeric data in Numpy, we commonly keep the data in array form, but there are some insta
输出始终为标准numpy.ndarray。 mafromtxt 始终设置usemask=True。输出始终为MaskedArray recfromtxt 返回标准numpy.recarray(if usemask=False)或MaskedRecords数组(如果usemaske=True。默认dtype为dtype=None,表示每个列的类型将自动确定。 recfromcsv 类似于recfromtxt,但使用默认的delimiter=","。 作者:张...
