Get Twisted: http://twistedmatrix.com/
Twisted is an event-based framework for internet applications which
works on Python 2.3.x, 2.4.x, and 2.5.x.
Twisted 2.5.0 is a major feature release, with several interesting new
developments and a great number of bug fixes. Some of the highlights
follow.

Either use a raw string: os.popen(r'c:\Program...) or double all
backquotes:

Interesting. The description I read said
Dear all,
I need to do a FFT on an array of 20k real values. Origin of the sampled
data is a sinus wave with light harmonics.
The goal is an frequency spectrum with the magnitudes of the first 50.

I addressed python like:
test_arr = src_data_dict[ channel ][0:19599]

What does it mean to me? How do I get to the wanted frequenca spectrum???
It's packed in the conventional FFT format. Here is a function in numpy (the
successor to Numeric, which I assume that you are using) that generates the
corresponding frequencies in the same packed format:
