Function Annotations: PEP-3107
I ran across a snippet of code demonstrating Python3's function annotations. The concept is simple but I can't think of why these were implemented in Python3 or any good uses for them. Perhaps SO can enlighten me?
How it works:
def foo(a: 'x', b: 5 + 6, c: list) -> max(2, 9):

The following code with fail in Python 3.x with TypeError: must be str, not bytes because now encode() returns bytes and print() expects only str.

How can you print a Unicode string escaped representation using p...
Below works on Python 2.6 but on Python 3.x it doesn't:

I would like to know if there is any Linux distribution where you can easily install and use Python 3. This means a distribution that will provide not only Python 3 binaries and updates but also python modules.
I know that probably we are not going to see any python 3 as the default python interpretor so soon but at least I would like t...
For practice, I'm trying to do some stuff in Python. I've decided to make a simple hangman game - I'm not making a GUI. The game would start with a simple input(). Now, I'd like next line to, beside asking for input, to delete the hidden word. I've tried using \b (backspace character), but it's not working. Something like:
word = input(...
All the stuff I am seeing points me towards writing clients.

I'm programming in Python 3 and I'm having a small problem which I can't find any reference to it on the net.
As far as I understand the default string in is utf-16, but I must work with utf-8, I can't find the command that will convert from the default one to utf-8.
I'd appreciate your help very much.

I am having the hardest time finding any resources that decently walk you through in terms of setting up a basic web service that can be accessed. Most of the stuff I am seeing is on the client side. The imports people talk about are all outdated and/or are buggy or rely heavily on established frameworks. I prefer SOAP so can anyone plea...

Pylint doesn't yet support Py3k, so am looking for an alternative.

The following code doesn't work in Python 3.x, but it used to work with old-style classes:
class Extender:
def extension(self):
print("Some work...")
class Base:
pass
Base.__bases__ += (Extender,)
Base().extension()
Question is simple: How can I add dynamically (at runtime) a super class to a class in Python 3.x?

Hi folks,
I'd like to use lxml library to validate XML Schemas in Python 3.1.2.
Since the Snow Leopard MAC OS comes with the Python 2.6.1 installed, firstly, I downloaded the Python 3.1.2 automated installer at http://www.python.org/ftp/python/3.1.2/python-3.1.2-macosx10.3-2010-03-24.dmg and installed it.

What are the current rules for writing python code that will pass cleanly through 2to3 and what are the practices that seem to be best suited to writing code that will not become mired forever in version 2.
I have read from the SciPy/NumPy forums that "100% test coverage" (unit testing) is important for many people, and I am not sure if...
Consider the following code (from here, with the number of tests increased):
