[sant527]

I have to pass lot of python codes to multiprocessing, how can i achive this

       import multiprocessing
	#pool = multiprocessing.Pool(joblib.cpu_count()) 
	pool = multiprocessing.Pool(4)
	results = pool.map(getScoreForEachMethod, arg_instances[0:100])
	pool.close()
	pool.join()

def getScoreForEachMethod(arg):
	logger_datetime_str = arg[0]
	symbolName = arg[1]
	symbolId = arg[2]
	daily = arg[3]
	weekly = arg[4]
	monthly = arg[5]
	methodId = arg[6]
	methodCode = arg[7]
	scoreSymbolParams = arg[8]
	lot_time = arg[9]
	customMethodobject=arg[10]

	allowed_param = {
	    "priceDaily": priceDaily,
	    "volumeDaily": volumeDaily,
	    "priceWeekly": priceWeekly,
	    "volumeWeekly": volumeWeekly,
	    "priceMonthly": priceMonthly,
	    "volumeMonthly": volumeMonthly,
	    "parameters": parameters,
	    "score": score
	}
	exec(customMethod,allowed_param)
	return allowed_param

so here customMethodobject is the customcode i have to run using exec where i want use seval.

the code is multiline and can use the allowed_params and some arthimetics

HOw can i do this
