title: how to loop over the elementary arithmetic symbols
body: <p>I want to check if 7 digits can get to 100 when putting elementary arithmetic symbols between them.</p>
  
  <pre><code>def is_hundred(n1,n2,n3,n4,n5,n6,n7):
      p = [+,-,*,/]
      for p1 in p:
          for p2 in p:
              for p3 in p:
                  for p4 in p:
                      for p5 in p:
                          for p6 in p:
                              if n1 p1 n2 p2 n3 p3 n4 p4 n5 p5 n6 p6 n7 == 100:
                                  return "success"
  </code></pre>
  
  <p>how can i replace the variables with the arithmetic symbols that are in the list?</p>
