Running python interactively from the Terminal alone is frustrating because you can't use arrow keys for history, no auto-complete, etc. You will probably want to use some IDE.

never have your data file overwritten again! include the following lines in your python code:

from time import localtime,strftime
timeAndDateStr = strftime("%d_%b_%Y_%H:%M", localtime())
filename = 'aBindingExpData_'    #include here whatever you want
filename = filename + timeAndDateStr  #filename will now have date time and year tacked on the end,
outputFileStream = open(filename, 'a')
#### e.g. 'aBindingExpData_04_Aug_2008_22:46'

This shell command to quit finder which can reduce occasional misses of screen refreshes: osascript -e 'tell application "Finder" to quit'

Here is a file Media:Matlab-python-xref.pdf‎ that gives equivalent code for doing array operations in MATLAB, Python, and R

clear all in MATLAB is [vars().__delitem__(_k) for _k in vars().keys() if not _k.startswith('_')] in python

If you are running from python prompt rather than IDE, execfile('myprogram.py') executes codefile

Good syntax guide here , Explanation of how default assignment creates reference rather than new variable here says to use deepcopy()
