RE: Question

I have already solved that problem. Sorry for not alerting you as to me of solving this issue. Thank you very much for the help. I was wondering if you would be interested in helping in the development of a Scipy / MyHDL hybrid. The advantage of this would be to develop FPGA logic with the ease

Garbage collection

Hi, I'm building a server with python, but coming from a c++ background, garbage collection seems strange. For instance, I have a manager looking after many objects in a dict. When those objects are no longer needed, I use del manager[objectid], hoping to force the garbage collector to perform
