TypeError: 'Bool'-Objekt ist nicht aufrufbar?

Question

Im mit Python 2.7 und pygame im ein Space Invaders Spiel, aber im immer diesen Fehler und sein sagen sein ein Problem mit der Linie

screen.blit(font.render(str(hits),True(255,255,255)),(400,320)) 

könnte mir jemand sagen, was das bedeutet und wie man es beheben machen versuchen, bitte ? der vollständige Code ist

Sie Komma vergessen , nach True - so jetzt Sie versuchen, Funktion aufzurufen True()

Aber True ist bool Objekt, nicht funktionieren - es ist also nicht "callable" - und Sie erhalten Fehler.
