Python numpy array of numpy arrays

Question

I\'ve got a problem on creating a numpy array of numpy arrays. I would create it in a loop:

a=np.array([])
while(...):
   ...
   b= //a numpy array generated         


        

Answer 1

we can try it also :

arr1 = np.arange(4)
arr2 = np.arange(5,7)
arr3 = np.arange(7,12)

array_of_arrays = np.array([arr1, arr2, arr3])
array_of_arrays
np.concatenate(array_of_arrays)
