Hello,
today I've released pysha3 0.2.1 [1]. It's a standalone version of the
SHA-3 extension that I merged into CPython's development branch (future

I am currently starting my PhD in software quality assurance and have been
doing a lot of reading round this subject. I am just trying to find out if
there is any relevant/current research in the production of a generic quality
assurance tool i.e. a tool/methodology that can accept many language

First, you should consider reading the documentation of
struct.unpack_from and struct.pack_into at
http://docs.python.org/library/struct.html quite carefully. It says,
that these commands take a parameter called offset, which names the
location of the data in a buffer (e.g. an opened file).

I am using python 2.6.
I need a way to make following code working without any ValueError .

Note: Number of values in the tuple will change dynamically.
I know in python 3, you can do `a, b, c, *d = (1, 2, 3)` and then d will
contain an

Using Python on Windows is a dream.
Python uses and needs the system, but the system does
not use Python.
Every Python version is installed in its own isolated
space, site-packages included and without any defined
environment variable. Every Python can be seen as a
different application.
