Re: [BangPypers] Calling Python script from C++.
if this thread is still active - instead of passing the argument , probably the argument can be extracted from a temporary file/buffer. a small code can be inserted to the python code sent as argument to PyRun_SimpleString() to read it. steve-391 wrote: Hi, On 02/25/2010 07:32 PM, lakshmi.chow...@bt.com wrote: Hi Zubin, [...snip...] In the function definition, I am taking 1 hard coded variable and needs to pass this variable along with the string(python code) to PyRun_SimpleString() and execute it.

could you give us a few more details? the deployment OS? cheers!!! Zubin On Thu, Feb 25, 2010 at 12:51 PM, lakshmi.chow...@bt.com wrote: Hi, We have a requirement of Calling Python script from C++.

Re: [BangPypers] Calling Python script from C++.
Hi Zubin, Thanks a lot for the quick reply. You are correct Zubin, we can execute python script individually as you described. But my requirement is that, Basically I want to call the python script from c++ program. In the c++ program, I am creating the multi threads and calling the thread function with a argument(argument contains the entire python code as a string, for example Def sayHello(name): Print Hello + name sayHello(arg)). In the function definition, I am taking 1 hard coded variable and needs to pass this variable along with the string(python code) to PyRun_SimpleString() and execute it. Could you tell me the solution how to map the argument to the string(python code) and pass to PyRun_SimpleString() and execute successfully?
