title: Python: needs more than 1 value to unpack
body: <p>What am I doing wrong to get this error?</p>
  
  <pre><code>    replacements = {}
      replacements["**"] = ("&lt;strong&gt;", "&lt;/strong&gt;")
      replacements["__"] = ("&lt;em&gt;", "&lt;/em&gt;")
      replacements["--"] = ("&lt;blink&gt;", "&lt;/blink&gt;")
      replacements["=="] = ("&lt;marquee&gt;", "&lt;/marquee&gt;")
      replacements["@@"] = ("&lt;code&gt;", "&lt;/code&gt;")
  
      for delimiter, (open_tag, close_tag) in replacements: # error here
          message = self.replaceFormatting(delimiter, message, open_tag, close_tag); 
  </code></pre>
  
  <p>The error:</p>
  
  <blockquote>
    <p>Traceback (most recent call last):<br>
    File "", line 1, in
    
        for doot, (a, b) in replacements: ValueError: need more than 1 value to
    unpack</p>
  </blockquote>
  
  <p>All the values tuples have two values. Right?</p>
