title: python refresh/reload
body: <p>This is a very basic question - but I haven't been able to find an answer by searching online.</p>
  
  <p>I am using python to control ArcGIS, and I have a simple python script, that calls some pre-written code.</p>
  
  <p>However, when I make a change to the pre-written code, it does not appear to result in any change. I import this module, and have tried refreshing it, but nothing happens.</p>
  
  <p>I've even moved the file it calls to another location, and the script still works fine. One thing I did yesterday was I added the folder where all my python files are to the sys path (using sys.append('path') ), and I wonder if that made a difference.</p>
  
  <p>Thanks in advance, and sorry for the sloppy terminology. </p>
