Thanks for the responses. Below is the code I have thus far. while the program runs glitch-free, it only results in the printing of the message: "NOTE *** No xls files in C:/Documents and Settings/smacdon/." as specified by my code. Any idea as to why it might be unable to find the .xls documents

ConfigObj is good - it (effectively) turns a dictionary into an ini file, and vice versa. There is also built in support for type conversion. See http://www.voidspace.org.uk/python/configobj.html See the ConfigPersist module which has functions to use ConfigObj for data persistence. It explains

A further thought, if you write the data to a file in the correct format, you can use import and reload to access the data later instead of repr. On 12/29/05, Tim Williams (gmail) <[EMAIL PROTECTED]> wrote: > On 30/12/05, Giovanni Bajo <[EMAIL PROTECTED]> wrote: > > > > > > >>> d = {'.\\sync_p
