title: Python def marked as invalid syntax
body: <p>Im working on a (in-shell) geometry calculator in Python, and I get a syntax error everytime marked as the <strong>def</strong> in the below code:</p>
  
  <pre><code>def scepm(r,h):#surface-area circular-prism(cylinder)comment s.o.f. only
      print(3.14159265358979323846264338327950*r**2+3.14159265358979323846264338327950*r*h)
  </code></pre>
  
  <p>It might be something obvious. If it is, can someone please point it out? thanks</p>
