This article is about how python implements iterator slicing. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Iterator slice

If you try to get a slice of the iterator, the system reports TypeError, indicating that the generator object cannot be subscribed, but the solution is simple:

Import itertools s = itertools.islice (range (50), 10, 20) # for val in s:.

Using itertools.islice, we can create an islice object, which is the iterator that produces the desired elements. It is important to note, however, that this consumes all generator items until the slice starts, and it also consumes all items in our "islice" object.

Using itertools.islice we can create an islice object which is an iterator that produces desired items. It's important to note though, that this consumes all generator items up until the start of slice and also all the items in our islice object.
