Is there a standard workaround to allow you to assign a sequence to a a single cell in PyObject array? from Numeric import * # Create a 2*5 array a = array([range(5),range(5)], PyObject) a[0,0] = 4 #OK - assigns an int to element 0,0 a[0,3] = {} #OK - assigns a dict # but, trying to assign an array to element 1,4 # (or any sequence) a[1,4] = array(range(10), Float) The last assignment causes, ValueError: array too large for destination error Doh!! Presumably its trying to treat this as an assignment to a slice. Is this a bug? Clearly it shouldn't be treated as a slice assignment since a[1,4] can only refer to an atomic element in the (2D) array, not a sequence. Cheers, Stuart
