Trouble installing scipy with macports

Question

I'm new to programming and trying to import scipy.

Problem:

When I try to import scipy in the python interpreter in terminal, it looks like this:

[GCC 4.2.1 Compatible Apple Clang 4.0 (tags/Apple/clang-418.0.60)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import scipy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named scipy
>>> 

I seem to have installed macports correctly. I can successfully import numpy the same way as above.

I originally installed scipy as per "macports" instructions on http://www.scipy.org/install.html

ie:

sudo port install py27-numpy py27-scipy py27-matplotlib py27-ipython +notebook py27-pandas py27-sympy py27-nose

Also I followed this post: Python will not recognize MacPorts installed packages

but could not seem to derive an answer for myself

To clarify:

When I run "which python" i get

/usr/bin/python

When I run "port contents py27-packagename" I get

Port py27-packagename is not installed.

Thanks in advance

MacPorts does not touch the system python when installing python modules. It does install these modules for its own version of python, which is in /opt/local/bin/python2.7 by default. You can make it the default python to be run when you type python in your shell using sudo port select --set python python27.
