You can also do it with ctypes only; too bad it's not really well documented. c_float is a type of a floating point number and it has * operator defined, so that c_float*4 is a type of a 4-element array of those numbers. So if you want to construct an array of floats from a list of floats, you can do it like this:
from ctypes import c_float x = [1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9] float_array_type = c_float*len(x) float_array = float_array_type(*x) print float_array -- http://mail.python.org/mailman/listinfo/python-list
