-On a list-type iterator creation expression, it is possible to specify an index range and a step to iterate over a subset of the list.
+When creating a list-type iterator expression, you can specify a range of indices and a step to iterate over a subset of the list.
 
 Indexing starts at 0. If the start index is not specified, it defaults to 0. If the end index is not specified, it defaults to the index of the last element of the list. If the step is not specified, it defaults to 1.
