WebAug 1, 2024 · To iterate over each element in my_list, we need an iterator object. So, we use the iter () function or __iter__ () method on my_list to generate an iterator object. The __iter__ () method takes an iterable object such as a list and returns an iterator object. Below is the syntax of using __iter__ () method or iter () function. WebApr 10, 2024 · "Generator expressions are currently not inlined in the reference implementation for the PEP, although it may be considered in future." - even then, generator inlining would be restricted to cases where the generator isn't exposed to other functions, like [x for x in (i**2 for i in l) if x < 1000]. Passing the generator to sum would …
