In cases where the intended meaning isn’t clear, using the full terms avoids ambiguity. 如上要点归纳: 1、生成器属于迭代器,故可以用next()函数获取值,也可以在for循环中使用。 2、生成器有两种形式:由生成函数创造的生成迭代器 或 生成器表达式。 generator iterator:An object created by a generator...
An object representing a stream of data. Repeated calls to the iterator’s next__() method (or passing it to the built-in function next()) return successive items in the stream. When no more data are available a StopIteration exception is raised instead. At this point, the iterator object...
Iterables can be used in a for loop and in many other places where a sequence is needed (zip(), map(), …). 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...
The Python “TypeError: 'float' object not iterable” error iscaused when you try to iterate over a floating point number as if it were an iterable object, like a list or a dictionary. To solve this error, use a range() statement if you want to iterate over a number. How do I fix...

An iterable is any Python object capable of returning its members one at a time, permitting it to be iterated over in a for-loop.Familiar examples of iterables include lists, tuples, and strings - any such sequence can be iterated over in a for-loop. We will also encounter important non...
Iterators in Python An Iterator is also an object which uses the__iter__()and__next__()methods, this is called the Iterator protocol. It is an iterable object with a state, meaning it remembers what stage it is at during iteration. ...
1. Explain the python iterators with an example? An iterator is an object that contains a countable number of values. An iterator is an object that can be iterated upon, meaning that you can traverse through all the values. Technically, in Python, an iterator is an object which implements ...
