A question of particular interest about python for loops. Engineering programs often require values at previous or future indexes, such as: for i in range(0,n): value = 0.3*list[i-1] + 0.5*list[i] + 0.2*list[i+1] etc... However I rather like the nice clean python syntax: for item in list: #Do stuff with item in list or for...

In his book Even Faster Web Sites Steve Sounders writes that a simple way to improve the performance of a loop is to decrement the iterator toward 0 rather than incrementing toward the total length (actually the chapter was written by Nicholas C. Zakas). This change can result in savings of up to 50% off the original execution time, depe...
