IDA, the Interactive Disassembler, is well known tool. It also comes in Freeware version, however, there are several limitations. For example, it is known, that IDA Freeware doesn’t support IDA Python, scripting language which brings the best from the IDA and from the Python world. For scripting, IDA Freeware supports only IDC, a “toy”  C-like language. In past I was wondering if it is possible to run Python even from IDA Freeware, Recently I played little bit more with IDC and I found a way how to pass data from IDA to external Python, and get back results to the IDA.
