Is there a simple stand alone python app I can use on my Kindle fire?

(it was recommended that I post this query here (originally posted on the tutor page)). Hello, I'm enjoying learning python, and would like to be able to study and practice on the go, using my kindle fire reader. (wifi enabled). Amazon does have an app, Qpython lite, but requires a live wifi connection to the internet to run. I'm looking for a simple python app, stand alone that i can run on my kindle, without an internet connection, just to practice while i learn. (Just a simple terminal, and text editor, and python? like ubuntu offers.) I've tried downloading portable python, and couldnt' get it to run ('can't run in DOS mode?'), I've tried downloading ubuntu to my kindle and couldn't, and tried downloading the whole 2.7 python app, but couldn't get it to run. I tried to root my kindle, but as I'm inexperienced in things tech, i'm not sure if I was successful, and not sure how this helps (if I was successful.) I have both windows 7 and ubuntu (dual boot) on my laptop, and can connect my kindle to the laptop via usb cable. I have "accept downloads from other applications" enabled on my kindle. On my kindle I have 'better terminal emulator pro' , ES file explorer, and droidedit. Any help is appreciated, I'm willing to follow step by step instructions to get python running on my kindle. I will supply any other details required. My kindle fire specs are : Model D01400 The Kindle Fire features a 7” display module from LG Display. The display is dual-sourced between LG Display and E Ink Holdings. The display touchscreen appears to be conventional capacitive glass on glass and the control IC on the touchscreen is from a previously unseen source. Meanwhile, the OMAP4430 applications processor from Texas Instruments is a dual-core RM Cortex-A9, 1GHz processor with IVA 3 Hardware Accelerator, SGX540 3D Graphic Core, 1080P 2D, 720P 3D and is produced in 45nm process geometry. Other key features include a 8GB eMMC NAND Flash Memory, 4Gbits of low power DDR2, a 3.7V battery with 4400mAh capacity (or about 16 Wh), and a module from Jorjin, which is based on Texas Instruments’ WL1270.

I want to add up the integers of this code in one line. For example, if I had the code integer = 0 denom = 10 again = "y" #sentinel: while again == "y" or again == "Y": integer = input("Enter a positive integer: ") while denom <= integer: denom = denom*10 while denom > 1: denom = denom/10 number = integer/denom integer = integer%denom print str(number) again = raw_input("Again? (Y/N): ") and inputted "54321," it would look like: Enter a positive integer: 54321 5 4 3 2 1 Again? (Y/N): n What I want to do is add up the "54321" so it comes out with "Sum of digits is 15." on one line. Thanks!

collections.Iterator __subclasshook__ does not check if next() is callable
by Byron Ruth April 1, 2013

I submitted this as bug last night: http://bugs.python.org/issue17584 and was *honored* to be rejected by Raymond Hettinger. However, I would like feedback on whether my concern (this bug) is justified and clarity if not. Consider: ```python class A(object): def __init__(self): self.r = iter(range(5)) def __iter__(self): return self @property def next(self): return next(self.r) ``` The `next` method is a property, however: ```python from collections import Iterator a = A() isinstance(a, Iterator) # True next(a) # TypeError: 'int' object is not callable ``` I am using `collections.Iterator` as the means to check if the object is an iterator, however I am not sure if that is _root_ problem here. My understanding of the iterator protocol is that is assumes the __iter__ and next *methods* are implemented. In the example, `A.next` is defined as a property, but is still identified as an iterator. To me, this is incorrect behavior since it's not conforming to the iterator protocol requirements (i.e. a `next` method, not a property). Raymond stated: "The design of ABCs are to check for the existence to required named; none of them verify the signature." I think I understand _why_ this is the case.. but I downstream libraries use `collections.Iterator` to determine if an object _is one_: see https://github.com/django/django/blob/master/django/utils/itercompat.py#L22… Who's job is it to check if `next` (and technically `__iter__`) are methods?
