        First,I highly recommend 嵩天's classes which is pretty good for guys like us .

Click this you will enter into songtian's classes .

A platform for practice .

Point:

ndarray的属性：
.ndim
.shape
.size
.dtype
.itemsize




ndarray的创建：
    前提import numpy as np
    np.array()
    np.arrange()
    np.ones(shape)
    np.zeros()
    np.full(shape,val)
    np.ones_like(a)
    np.zeros_like(a)
    np.full_like(a,val)

ndarray的变换：
    .reshape()
    .resize()
    .flatten()

    .astype()

See you next time , ciao !
