A nested loop performs faster than a flattened one because it takes advantage of spatial locality, which is the principle that data that is close to each other in memory is also likely to be close to each other in time. When a nested loop iterates through an array, it ...
Webdef f4 (list): string = "" lchr = chr for item in list: string = string + lchr (item) return string. As expected, f4 () was slower than f3 (), but only by 25%; it was about 40% faster than f1 () still.
