title: Invalid character in identifier syntax error
body: <p>So we have this  code that we're trying to use to load from a pickle '.dat' file. Can anyone explain why we are getting this error?</p>
  
  <p>Here is the code:</p>
  
  <pre><code>if os.path.exists('teacherdata.dat') == True:
      with open('teacherdata.dat', rb) as f:
          teacherdata = pickle.load(f) 
  </code></pre>
  
  <p>Here is the error:</p>
  
  <pre><code>﻿﻿    if os.path.exists('teacherdata.dat') == True:
         ^
  SyntaxError: invalid character in identifier
  </code></pre>
  
  <p>Thanks in advance</p>
