In python..

The slice_ gen generator takes one iterable and a start, stop and step values (all int, with the same meanings as the values in a slice: [start:stop:stepl, except start and stop must be non-negative and e. step must be positive; raise an AssetionError exception if any is not). It produces all the values in what would be the slice (without every putting all the values in alist and slicing it). For example for i in slice gen('abcdefghijk', 3,7,1): print (i,end-i ') prints the 4 values: 'd', 'e', 'f', and 'g':the 3,4hst and 6 values (start counting at the0h value) rd /th pnn Hint: you may use the range class. Even if the iterable is infinite, this generator/decorator should work and produce a finite number of values
