). When an iterable object is passed as an argument to the built-in function iter(), it returns an iterator for the object. This iterator is good for one pass over the set of values. When using iterables, it is usually not necessary to call iter() or deal with iterator objects ...
Iterable in Python¶ Iterable is a sequence that can be iterated over, i.e., you can use afor loopto iterate over the elements in the sequence: forvaluein["a","b","c"]:print(value) Examples are: Lists Tuples Strings Dictionaries Sets Generators Iterable objects are also known as i...
In async iterators, the .__anext__() method must return the next object, which must be awaitable. Python defines awaitable objects as described in the quote below: An object that can be used in an await expression. [It] can be a coroutine or an object with an .__await__() ...
python中iterable和iterator(补充enumerate函数) iterable:可迭代对象 可以一个一个的返回它的成员,比如list,str,tuple,dict,file objects 它可以在for loop种使用,for loop in后面接的必须是一个可迭代对象 iterator:迭代器 是一个表示数据流的对象,可以使用next函数不断的从这个对象里面获取新的数据 前者是一个数据...

直接引用python的官方文档的定义(docs.python.org/3.8/glo): An object capable of returning its members one at a time. Examples of iterables include all sequence types (such as list, str, and tuple) and some non-sequence types like dict, file objects, and objects of any classes you define ...
(), it returns an iterator for the object. This iterator is good for one pass over the set of values. When using iterables, it is usually not necessary to call iter() or deal with iterator objects yourself. The for statement does that automatically for you, creating a temporary unnamed ...
This is the third in a multi-part series on ArcPy cursors; particularly, working with ArcPy cursors as iterable objects in Python. The first part in the series

Iterables in Python Iterables are objects which can be looped/iterated over by using a for loop. Iterables contain data or have value, where executing a for loop will perform an iteration, producing outputs one after another. An iterable implements the__iter__()method and returns an iterator...
