All of my programming is data centric. Data mining is foundational
there in. I started learning computer science via Python in 2003. I
too was concerned about it's performance, especially considering my
need for literally trillions of iterations of financial data tables
with mathematical algorithms.
I then leaned C and then C++. I am now coming home to Python realizing
after my self-eduction, that programming in Python is truly a pleasure
and the performance is not the concern I first considered to be.
Python is very easily extended to near C speed. The Idea that FINALLY
sunk in, was that I should first program my ideas in Python WITHOUT
CONCERN FOR PERFOMANCE. Then, profile the application to find the
"bottlenecks" and extend those blocks of code to C or C++. Cython/
Pyrex/Sip are my preferences for python extension frameworks.
Numpy/Scipy are excellent libraries for optimized mathematical
operations. Pytables is my preferential python database because of
it's excellent API to the acclaimed HDF5 database (used by very many
scientists and government organizations).
As for GUI framework, I have studied Qt intensely and would therefore,
very highly recommend PyQt.
After four years of intense study, I can say that with out a doubt,
Python is most certainly the way to go. I personally don't understand
why, generally, there is any attraction to Java, though I have yet to
study it further.
