Another highly useful function is -\function{reduce()}. A classical use of \function{reduce()} -is something like - -\begin{verbatim} -import sys, operator -nums = map(float, sys.argv[1:]) -print reduce(operator.add, nums)/len(nums) -\end{verbatim} - -This cute little script prints the average of all numbers given on the -command line. The \function{reduce()} adds up all the numbers, and -the rest is just some pre- and postprocessing. +\function{max()}/\function{min()}. On the same note, note that \function{float()}, \function{int()} and \function{long()} all accept arguments of type string, and so are |
