[Tutor] Doubts about installing python3.1 in squeeze

[Markos]

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.

Sorry, typing is hard.
*You will need to use virtualenv

You can't use apt-get or similar to install 3.1.
You will need to virtualenv.

Sadly, this is not the modern way to do it.  These days, it’s
recommended to use something like Flask, or Django, or whatnot.  CGI
is ancient, and problematic.

…or maybe not.  The correct way is compiling it on your own (the usual
Unix way, but using `make altinstall` for the install step).
virtualenv won’t help in this case, it’s not what virtualenv is for.

If you wanted to do it dynamically you'd have a file called
something like mypage.cgi which looked like:

print("My web page")
print("This the body")

And provided the web server was configured to run python
on cgi files you could access it as

http://myserver.addresss/mypage.cgi

CGI is still how many frameworks operate under the covers.
They just hide it well. But I agree that using a framework
is the only sane way to build a significant web app nowadays
and I was not promoting original CGI as a solution.

However, the OP seemed to be asking about the low level
details of how a web app works and using a framework
(both by design and intent) hides all of that from you
whereas an old fashioned CGI app exposes it.
Hence my illustration.
