No: pow won't work on lists. It will work on (a) numbers (pow(2, 3) - > 8), or (b) numpy arrays, e.g.: >>> import numpy as np >>> x = np.array([0.1, 0.5, 0.4]) >>> y = np.array([3, 24, 18]) >>> pow(x, y) array([ 1.00000000e-03, 5.96046448e-08, 6.87194767e-08]) >>> x ** y # exactly equivalent array([ 1.00000000e-03, 5.96046448e-08, 6.87194767e-08]) > (ii) The second question is, if I have another set of variables, > > variable1=random.random() > variable2=random.random() In this case 'variable1' and 'variable2' are Python floats, so yes, you can multiply them directly. (BTW, you can always experiment directly at the Python interactive prompt to answer this sort of question.) Mark -- http://mail.python.org/mailman/listinfo/python-list
