Are parts of NumPy and/or SciPy programmed in C/C++?
And how does the overhead of calling C from Python compare to the overhead of calling C from Java and/or C#?
I'm just wondering if Python is a better option than Java or C# for scientific apps.
If I look at the shootouts, Python loses by a huge margin. But I guess this is because they don't use 3rd-party libraries in those benchmarks.
I've used Python for data processing and analysis for a couple of years now so I would say it's certainly fit for purpose.
What are you trying to achieve at the end of the day? If you want a fast way to develop readable code, Python is an excellent option and certainly fast enough for a first stab at whatever it is you're trying to solve.
Why not have a bash at each for a small subset of your problem and benchmark the results in terms of development time and run time? Then you can make an objective decision based on some relevant data ...or at least that's what I'd do :-)
