How to get source package with aptitude on linux?

I can get source packages using apt-get source , but there a way to do this using aptitude ? Also I downloaded the .deb package for python2.6 using aptitude and then unzipped it using ar.

aptitude download python2.6
ar xv python2开发者_运维百科.6_2.6.5-1ubuntu6_i386.deb

I also downloaded the python source using apt-get

sudo apt-get source python2.6

The contents of both the downloads are different. Why ?

aptitude download python2.6 retrieves the binary package for python2.6.

apt-get source python2.6 retrieves the source package that generates the binary package python2.6.

Source downloads will include the original source tarball, the debian diff and the signed certificate file.

apt-get source packagename

apt-get source does not interact with the package system so mixing apt-get and aptitude is fine in this case.

You also do not have to be root to use apt-get source.

The .deb package is the binary package, that is, the results of compiling the source package. It is the thing that would be installed if you did aptitude install <package>.

It does not appear that aptitude can download source packages.
