body: <p>Im using python 2.7 and pygame im trying to make a space invaders game but im getting this error and its saying its a problem with the line</p>
  
  <pre><code>screen.blit(font.render(str(hits),True(255,255,255)),(400,320))
  </code></pre>
  
  <p>could someone tell me what this means and how to fix it please? the full code is</p>
