Python 3.0 is in beta with a final release coming shortly. Obviously it will take some significant time for general adoption and for it to eventually replace 2.x.
I am writing a tutorial about certain aspects of programming Python. I'm wondering if I ...

I'm running windows and the shell/os automatically runs python based on the registry settings when you run a program on the command line. Will this break if I install a 2.x and 3.x version of python on the same machine?

As far as I know Python runs off of the commandline using the PATH variable as opposed to the version of python you want to use by default, and check the "always use this program to open this kind of file" checkbox.

Maybe I'm old school, but when I sit down to really tackle a new language I like to buy whatever the definitive book is for that language rather than mess around with tutorials and online intro "toys" to the language.

Imho you're safe to start learning python 2.

I'm a PhD student and use Python to write the code I use for my research. My workflow often consists of making a small change to the code, running the program, seeing whether the results improved, and repeating the process. Because of this, I find myself...

The were definitely performance issues in Python 3.0, but they were largely resolved in Python 3.1.

I have a large infrastructure that is written in Python 2.6, and I recently took a stab at porting to 3.1 (was much smoother than I expected) despite the lack of backwards compatibility.

IOW, port to 3.x in a way so that the code remains compatible with 2.x.
I would expect cycle, it could be a while.
For your code, I recommend to keep it in 2.x changes).
Jython will not support Python 3.x in the near future.

Just saw a question about, hello world on python!
The answers say's, this is not support in py 3.x. What does this mean, is python not backward compatible? If it is not, I think this is a very big issue, from acceptability and learning point of view.

Is there any reason to prefer unicode(somestring, 'utf8') as opposed to somestring.decode('utf8') ?
My only thought is that .decode() is a bound method so python may be able to resolve it more efficiently, but correct me if I'm wrong.

I am trying to make an HTTP request in Python 2.6.4, using the urllib module. Is there any way to set the request headers?
I am sure that this is possible using urllib2, but I would prefer to use urllib since it seems simpler.

There isn't any way to do that, which is precisely the reason urllib is deprecated in favour of urllib2 .
Check out the documentation of urllib2.Request.
I don't think so, but urllib2 can.

According to python docs it works like.
In python 2.7 there is going to be a format specifier for thousands separator.
I just want to add this for future reference.
There are already some good answers in here.
