If the elements of mylist can be compared (es. not complex values), then this can be a solution for you:
from math import sin as f mylist = [float(2*i)/10 for i in xrange(10)] pairs = [(f(x), x) for x in mylist] ymax = max(pairs)[1] print pairs, "\n" print ymax You can also try this, for Py2.4: print max((f(x), x) for x in mylist)[1] Bye, bearophile -- http://mail.python.org/mailman/listinfo/python-list
