[Pythonmac-SIG] HFS versus POSIX paths (changed from fixing the documentation)

I changed the topic so many can avoid it and we don't bore them to  
tears ;-)

I am writing an app combining excel and python/appscript to fetch  
quotes from the web and value stock portfolios .
But I give up on using appscript with Excel--some things just don't  
work because I think the terminology is seriously warped if no  
broken. Applescriptworks but appscript doesn't.

I instead build a text Applescript from strings and use popen2 to  
invoke osascript like this example which reads in the stock symbols  
from a named range in an excel spreadsheet:

     def readSymbolList(self, workbook, worksheet, range):
         _getSymbolsScript = """tell app "Microsoft Excel"
              return Value of Range "%s" of Worksheet "%s" of  
Workbook "%s"
             end tell"""
         # read symbols from spreadsheet
         cout, cin = popen2.popen2( "/usr/bin/osascript -e \'%s\'" % \
             (_getSymbolsScript % (range, worksheet, workbook)))
         symbols = cout.readline()[:-1]
         symbols = re.sub(",\s",",",symbols)
         if (self.DEBUG):
             print __module__, "::","symbols=", repr(symbols)
         # create symbolList
         symbolList = []
         symbols = string.split(symbols, ",")
         if (self.DEBUG):
             print __module__, "::","stocks=", repr(symbols)
         for symbol in symbols:
             if (symbol != '0'):
                 symbolList.append(symbol)
         cout.close()
         cin.close()
         return symbolList

If you really desire to you can but I just wrote a quick hack using  
re.sub() that correctly converts the paths I use so my needs are met.
