I have lists (and list of lists) as standard data-structure (most of my functions returns list/list of lists). But now I have to use some Numpy functions. Do I have to convert all lists to numpy array before using any function from numpy/scipy. For example
>>>x= [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
>>>y= [ 1, 10, 20]
>>>dot(x,y)
#array([ 81, 174, 267])
>>>X_np=array(x)
>>>y_np=array(y)
>>>dot(x_np,y_np)
#array([ 81, 174, 267])
As in this case dot(x,y) and dot(x_np,y_np) gave same result, so using list instead of numy array doesn't make difference....but is this the case for all numpy/scipy functions or I have to do my_np_array= array(my_list) before calling any/all numpy/scipy functions?
