I use MacPorts. Also popular are Brew and Fink. You can even use them all at 
once; they install to separate trees.

My Python 3 comes from MacPorts.

As pointed out elsewhere, OSX ships with "Terminal" as a terminal emutator.  
Another popular terminal emulator is iTerm2, which is what I prefer. You can 
run X11 also, and use any of the many terminal emulators that run in it, though 
the experience is clunkier.

As far as shells go, OSX ships with /bin/sh, /bin/bash and /bin/zsh. Or for the 
perverse, /bin/csh and /bin/tcsh (it is, after all, a BSD derived OS). I use 
zsh, getting my copy from MacPorts instead of OSX's native one.

So it is a perfectly normal UNIX system in this regard.
