(r,) and (r,1) just add (useless) parentheses but still express respectively 1d. 或者说如果我们想打印成python list，他该长成什么样子？ 假设你的np.array ()就是一个nested list, 那么它的shape,第一个值，或者说tuple第一个元素 int _0 就是对应于看你的nested list第一层. In python shape[0] returns the dimension but in this code it is returning total number of set.

Please can someone tell me work of shape[0] and shape[1]? Below is the code i am using to add the shape:. The shape attribute for numpy arrays returns the dimensions of the array.
I am trying to add a shape at a specific cell location but cannot get the shape added at the desired location for some reason.
Objects cannot be broadcast to a single shape it computes the first two (i am running several thousand of these tests in a loop) and then dies. 8 list object in python does not have 'shape' attribute because 'shape' implies that all the columns (or rows) have equal length along certain dimension. If y has n rows and m columns, then y.shape is (n,m). Let's say list variable a has.
X.shape[0] gives the first element in that tuple, which is 10. Yourarray.shape or np.shape() or np.ma.shape() returns the shape of your ndarray as a tuple; And you can get the (number of) dimensions of your array using yourarray.ndim or. The dimensions of the array.
