list(1) isn't iterable, but list('a') is. Quirk of Python or is there a reason for this?

This is a case where
list() is not the same as using bare brackets
[ ] to define a list. The built-in function
list() iterates over an single object and returns a list of the objects items. The brackets
[ ] creates a list from the literal and object references listed between the brackets.
To get a list of of the number 1 using the
list() function pass the integer as a tuple:
$ python3 Python 3.4.3 (default, Oct 14 2015, 20:28:29) [GCC 4.8.4] on linux Type "help", "copyright", "credits" or "license" for more information. >>> list(1) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'int' object is not iterable >>> list((1, ))
