WitrynaOn Python 3 you can use the itertools islice to slice the dict.items () iterator import itertools d = {1: 2, 3: 4, 5: 6} dict (itertools.islice (d.items (), 2)) {1: 2, 3: 4} Note: this solution does not take into account specific keys. It slices by internal ordering of d, which in Python 3.7+ is guaranteed to be insertion-ordered. Share Witrynaislice () creates an iterator (let’s call it a slicer) that traverses the passed sequence until it yields page_size elements; list () fetches elements from the slicer, thus creating a page; since islice () runs on top of the main iterator, the next time it is called, it will continue from the same place where it left off before;
