Mar 27, 2012 · An iterable is an object that has an iter() method which returns an iterator. It is something that can be looped over. Example : A list is iterable because we can loop over a list BUT is not an iterator; An iterator is an object that you can get an iterator from. It is an object with a state so that it remember where it is during iteration

This is how the term "iterable" is defined in Python's doc: iterable. 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 with an __iter__() or __getitem__() method.

if iterable(obj): # act on iterable else: # not iterable as you would do with thecallable function. EDIT: if you have numpy installed, you can simply do: from numpy import iterable, which is simply something like. def iterable(obj): try: iter(obj) except: return False return True

Jul 28, 2011 · On the flip side, Iterable is another interface, which, if implemented by a class forces the class to be Iterable and is a target for For-Each construct. It has only one method named iterator() which comes from Iterator interface itself. When a collection is iterable, then it can be iterated using an iterator. For understanding visit these:

Sep 19, 2013 · Keep in mind that the word iterable specifically refers to the iterable protocol, though there exist different ways to loop over objects. The following list is not exhaustive: arr.forEach(func) runs a function on each non-empty slot in an array (see sparse arrays here).

Oct 16, 2018 · The typing.Iterable is generic, so you can say what it's an iterable of in your type annotations, e.g. Iterable[int] for an iterable of ints. The collections iterable is an abstract base class. These can include extra mixin methods to make the interface easier to implement when you create your own subclasses.

Mar 25, 2011 · this is how we make a class object iterable. provide the class with a iter and a next() method, then you can iterate over class attributes or their values.you can leave the next() method if you want to, or you can define next() and raise StopIteration on some condition. e.g:

The ONLY way to create an existing Collection derivative implementing Iterable is to use a loop (except you use anonymous classes as described above) or you instantiate an Iterable implementing class whose constructor allows a primtive type array (because Object[] doesn't allow arrays with primitive type elements) but as far as I know, the Java ...

Oct 8, 2010 · For example if data is a value returned from a function, then make sure that function returns an iterable object (such as list, numpy ndarray, pandas DataFrame etc.). If data is the value returned from some API call, make sure to check …

The extend method for a list tries to iterate over the (single) argument, and int is not iterable. (Meanwhile, of course, the append method just adds its (single) argument, so that works fine. The list comprehension is quite different internally, and is the most efficient method as the list-building is done with much less internal fussing-about.)
