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 tell me the solution how to map the argument to the >> string(python code) and pass to PyRun_SimpleString() and execute >> successfully? >> > > Is there any specific reason you choose to read the entire file and > execute it > using PyRun_SimpleString() as opposed to the more traditional and standard > methods of using fork()+exec*() or system() functions ? > > cheers, > - steve > > -- > random non tech spiel: http://lonetwin.blogspot.com/ > tech randomness: http://lonehacks.blogspot.com/ > what i'm stumbling into: http://lonetwin.stumbleupon.com/ > ___ > BangPypers mailing list > BangPypers@python.org > http://mail.python.org/mailman/listinfo/bangpypers > > -- View this message in context: http://old.nabble.com/Re%3A-Calling-Python-script-from-C%2B%2B.-tp27715952p27768904.html Sent from the BangPypers - Bangalore Python Users Group mailing list archive at Nabble.com. ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers

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?

Re: [BangPypers] Calling Python script from C++.
Hi Zubin, Deployment OS is RedHat Linux. Here is the python file : Hello.py Def sayHello(name): Print "Hello" + name sayHello(arg) and In c++ file, I am catching all the lines from the python file in string buffer and calling the PyRun_SimpleString(stringbuffer). It is working fine without passing any argument. But I want to send the argument to this python file from c++ file. Could you tell me how can I pass arguments to python file?
