Hi,
I'm learning Python and I'm using Debian 6.0 (squeeze)
The installed version is 2.6.6. (python -V)
I have seen some recommendations for beginners to invest in version 3.
I found package of Python 3.1 in repository for squeeze.
I am considering installing Python 3.1 with
apt-get install python3.1
But I found the site
http://www.circuidipity.com/python2-and-python3.html information on
how to keep the two versions using virtualenv.
Also I found in the /usr/bin python2.5 and python2.6
And in /usr/lib python2.4, python2.5 and python2.6
Can I just run apt-get install python3.1 or should I do any other
configuration?
I'm confused.
Are there any risk to install python3.1 and some programs stop working
on my debian squeeze?
Thanks for any tips?
Markos
On Ubuntu both v2 and v3 are installed by default.
Have you tried typing
python3
on the command line?
If you get the interpreter, it's installed.
Then you just have to use a different shebang line in your code files:
#!/usr/bin/env python3
I don't have a debian system close at hand to test this myself.

Dear,
Thanks everyone for the tips.
I tried to install python3.1 with the command
apt-get install python3.1
and use the shebang #!/usr/bin/env python3 in the source code header.
It works.
But to use Tkinter I also had to install the package python3-tk
apt-get intall python3-tk
Now I have in /usr/bin
python python3 python2.5 python2.6 python3.1
python is a link to python2.6 and python3 is a link to python3.1
Until now everything is working.
Markos
