The python and C programs are NOT equivalent. (surface level they are: they
both calculate the triangular number of N, N
Thanks,
But the different is very significant!!!
so?

Hi,
What do you mean?
the python and C programs are not equivalent?

This is a fascinating subject. Firstly:
a lot of people think that C (or C++) is faster than python, yes I agree,

if you look at raw execution speed, then this is absolutely correct. The
reasons for this are many and complex, but people who use this as a
standalone reason to avoid Python
Also interestingly, you can see the language breakdown on the right hand
side of https://github.com/numpy/numpy/ :
Python 62.5%
C 35.3%
C++ 1.0%
Cython 0.9%
Shell 0.2%
Fortran 0.1%
Much of the Python code is tests.

Hi,
Simply check the original Numpy aka Numerical Python docs where it’s
comprehensively explained that the library is implemented in C with a thin
Python wrapper. The docs were written circa ‘98 by the original library author.
The library was optimised over a long period before being
Yeah it uses BLAS, you can read about it here

Hi,
a lot of people think that C (or C++) is faster than python, yes I agree,
but I think that's not the case with numpy, I believe numpy is faster than
C, at least in some cases.
*Is there another explanation ?Or where can find a doc speaking about the
subject?*Thanks a lot
