There are several ways to do this and it depends on your application which is most practical. If w assume yyou want to access the C code from Python then: 1) Write a Python module in C and then import it into Python 2) Write a C library and call it from Python (using the ctypes Python module for example) 3) Write a C program and then call it from Python using the subprocess library. These are in reverse order of difficulty (ie 3 is easiest). 1 is best if you need to access the C code from several Pyhon programs. 2 is best if you need to access the C code from both Python and C 3 is best if you only have a few high-level tasks to perform in C, and want the simplest integration. If you want to access Pyhon code from C then you need 1) Embed the Python intetrpreter in your C code ande call it using the Python API. 2) Write a Python service framework that can be called from C using fork/system or whatever 3) Create a Python http server that you can call from C (or any other language) using AJAX 1) Most difficult but best performance and loweset resource usage, 2) Relatively easy but resource heavy 3) Easiest if you know web technology and best if you might need several programs to access it, but probably slowest too. There are other options too (Steve mentioned Cython and there are tools like Boost too) > 3)I need PYTHON for the following purposes: > A)EMBEDDED SYSTEM PROGRAMMING See the comments above re integrating C and Python. > B)SCIENTIFIC PROGRAMMING > C)IMAGE AND VIDEO PROCESSING > D)DATA VISUALIZATION Down to here suggests you get a distribution with all the SciPy stuff included such as Anaconda or Entropy.

That then leaves application specific libraries that you would need to describe your needs in more detail for anyone to give recommendations. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
