Unexpected behavour when making array of 2D arrays, of similar dimension

Question

MWE:

def showArrayOfList(a,b,c):
    wlist = [np.zeros((szNext,szThis)) for (szThis,szNext) in [(a,b),(b,b),(b,b),(b,c)]]

    print \"wlist:\",         


        

Answer 1

A more consistent way of creating wArray is to initialize it to a (4,) object array, and fill it term by term:

n = len(wlist)
wArray = np.empty((n,), dtype='O')
for i in range(n):
    wArray[i] = wlist[i]

This isn't as pretty as asarray(wlist), but it splits the 3 dimensions in the same 1,2 manner regardless of what a,b,c are.
