You can use the subprocess.STARTUPINFO class to hide the text from the console window. It can be passed as an option to subprocess.Peopen(). Try this:
def interpreter1():
b=que2.get(block=True)
a=que1.get(block=True)
print "prameters are :" ,a ,b ,"\r\n"
c='python C:\\workspace\\Project_Interpreter\\Tool-v1.0.py -s %s %s'%(b,a)
startupinfo = subprocess.STARTUPINFO()
startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
ps=sp.Popen(['cmd','/K',c] , creationflags=0, shell=False, startupinfo=startupinfo, stdout=PIPE, stderr=sp.STDOUT, stdin=PIPE)
texte01= ps.stdout.readlines()
