title: Beginner Python: Saving an excel file while it is open
body: <p>I have a simple problem that I hope will have a simple solution.</p>
  
  <p>I am writing python(2.7) code using the xlwt package to write excel files. The program takes data and writes it out to a file that is being saved constantly. The problem is that whenever I have the file open to check the data and python tries to save the file the program crashes. </p>
  
  <p>Is there any way to make python save the file when I have it open for reading?</p>
