[Tutor] Suggestions as to how to read a file in paragraphs

[Kent Johnson]

You could read the file by lines and accumulate lines in a list until you 
find a paragraph break. Then look at the accumulated lines and see if you 
want to print it. Something like this (assuming a blank line is a paragraph 
break):

     linesInPara = []

     for line in f:
         if not line.strip():
             processParagraph(linesInPara)
             linesInPara = []
         else:
             linesInPara.append(line)

     if linesInPara:
         processParagraph(linesInPara)
