Re: speeding things up with C++

Thanks this is good news. I think my C/C++ background is sufficient to manage to figure things out if I RTFM carefully. Basically I want to pass in a Python list of integer tuples, create an STL container full of equivalent tuples, apply some processor- intensive algorithm to said list of tuples,

Re: speeding things up with C++

I wonder if Jython might be the answer? Java is going to be faster than Python for the time-critical part of my program. Does anybody have experience getting data structures like nested lists / tuples into a java routine from a running jython program (and then back again)? -- http://mail.python.o
