关于np.array是可变对象还是不可变对象, 官方文档中的意思应该是可变对象: Just like in other Python container objects, the contents of an array can be accessed and modified by indexing or slicing the array. Unlike the typical container objects, different arrays can share the same data, so changes ...
numpy.concatenate((a1, a2, ...), axis=0, out=None)Join a sequence of arrays along an existing axis. 注意:除axis以外,其他维度必须完全相等 numpy.stack(arrays, axis=0, out=None)Join a sequence of arrays along anew axis. numpy.vstack(tup)Stack arrays in sequence vertically (row wise). ...

Method 7: Using Numpy ModuleNumpy which is commonly used for handling single and multi-dimensional arrays of data is used here along with its flip method. Initially we need to convert the input/original tuple to a numpy array and then flip it using the flip() method. After that we ...
But if the arrays seem similar (ie. their first dimension is the same), but they are not 'broadcastable' an error is thrown. It seems strange, that is possible to pass a random set of array, but it does not work if the arrays are somehow similar and numpy tries to broadcast them ...
