Theshapeattribute for numpy arrays returns the dimensions of the array. IfYhasnrows andmcolumns, thenY.shapeis(n,m). SoY.shape[0]isn. In [46]: Y = np.arange(12).reshape(3,4) In [47]: Y Out[47]: array([[0,1,2,3], [4,5,6,7], [8,9,10,11]]) In [48]: Y.shape ...

Here, a NumPy arraymy_arrayis created, and then its shape is retrieved using the.shapeattribute. This method works seamlessly for multi-dimensional arrays, providing both the number of rows and columns. Use Recursion to Get the Shape of Irregularly Nested Lists in Python ...
Python“AttributeError: 'list' object has no attribute 'shape'” 发生在我们尝试访问列表上的shape属性时。 要解决该错误,请将列表传递给numpy.array()方法以在访问 shape 属性之前创建一个 numpy 数组。 下面是一个产生上述错误的示例代码 my_list = [1,2,3]# # ⛔️ AttributeError: 'list' object...
Learn about the shape attribute of NumPy ndarrays, how to use it to get the dimensions of an array, and its significance in data manipulation.
Following the below example, first, you can convert the list into a NumPy array using thenp.array()function. Then you can use theshapethe attribute of the NumPy array to get the shape of the array as a tuple of integers. Finally, you can access the tuple’s elements to get the list...
