Is it possible to autodetect python's version used in current file? Maybe it's somehow noted in script's first lines or $! shebang line?

I think it is not good. Even sometimes some people will write shebang header
like bellowing:
#!/usr/bin/env python3

But this is not a convention. And there is not other ways to detect current
file's python version.

And I hope viewdoc can add command for python, viewdoc has command :ViewDoc_perl
for perl, but no command for python.
Two command: :ViewDoc_python (default for python3) and :ViewDoc_python2.

I've checked how it works on my OS (Gentoo), and it differs from yours:

• Gentoo provide system-wide way to switch between different versions of same package if they installed simultaneously using eselect python set python3.2. This result in changing pydoc command too - it show docs for selected python version.
• There is no pydoc3 command on my system, but there are pydoc2.7 and pydoc3.2 commands.

So, it looks like running pydoc is sane defaults for any python version.
In case multiple python versions installed simultaneously and you need to view documentation for non-default python version actual command name (pydoc3 or pydoc3.2) is system-dependent and shouldn't be hardcoded in this plugin. Instead, user should be able to manually define any 'pydoc' command instead of default one. Something like this:

let g:viewdoc_pydoc_cmd = "pydoc3.2"
