	Well, one thing is that an installer with "cp32" in the filename is for 
Python 3.2.  For Python 3.4 you need the one that says "cp34".

Thanks Paul. Works perfectly.
I should have been able to work that out for myself, but my format was 
wrong.
Cheers.

Hhm, that is one of the requirements, see under the Windows section:
http://matplotlib.org/users/installing.html?highlight=requirements

You should be able to install them with 'pip' - e.g. 'pip install six'

numpy is a bit more of a hazzle, in the past Christoph Gohlke's site had 
.exe's but there are now wheels, so you need to download the correct one 
(win32 and py3.4) and then use pip to install it.

Per your instructions, I downloaded [] and installed using the 'wizard'.  The file I'm trying to execute is currently in a PyCharm project, and the Error Trace I get is as follows:
C:\Python34\python.exe "C:/Users/Ralph/PycharmProjects/anuASTRO4x/src/Euler's Method.py"Traceback (most recent call last):
  File "C:/Users/Ralph/PycharmProjects/anuASTRO4x/src/Euler's Method.py", line 21, in <module>
    import pylab # This program requires the matplotlib python library for the plots.
  File "C:\Python34\lib\site-packages\pylab.py", line 1, in <module>
    from matplotlib.pylab import *
  File "C:\Python34\lib\site-packages\matplotlib\__init__.py", line 105, in <module>
    import six
ImportError: No module named 'six'
Euler's Method

'from matplotlib.pylab import *' calls '__init__-py' and tries [unsuccessfully] to 'import 'six'.
What do you suggest I do to correct the ImportError: No module named 'six' ?Thanks for the help, Ralph

You'll probably have an easier time if you install one of the
"batteries included" Python distributions listed here -
http://www.scipy.org/install.html

Then you can get started without needing to learn how and where Python
packages are installed.

Cheers,
Scott
