Python: how to determine if an object is iterable?

Is there a method like isiterable? The only solution I have found so far is to call: hasattr(myObj, '__iter__') but I am not sure how foolproof this is.
Checking for __iter__ works on sequence types, but it would fail on e.g. strings in Python 2. I would like to know the right answer too, until then, here is one possibility (which would work on strings, too): try: some_object_iterator = iter(some_object) except TypeError as te: print(some_object, 'is not iterable') The iter built-in checks for the __iter__ method or in the case of strings the __getitem__ method. Another general pythonic approach is to assume an iterable, then fail gracefully if it does not work on the given object. The Python glossary: Pythonic programming style that determines an object's type by inspection of its method or attribute signature rather than by explicit relationship to some type object ("If it looks like a duck and quacks like a duck, it must be a duck.") By emphasizing interfaces rather than specific types, well-designed code improves its flexibility by allowing polymorphic substitution. Duck-typing avoids tests using type() or isinstance(). Instead, it typically employs the EAFP (Easier to Ask Forgiveness than Permission) style of programming. ... try: _ = (e for e in my_object) except TypeError: print(my_object, 'is not iterable') The collections module provides some abstract base classes, which allow to ask classes or instances if they provide particular functionality, for example: from collections.abc import Iterable if isinstance(e, Iterable): # e is iterable However, this does not check for classes that are iterable through __getitem__.
