Heh, be careful when assuming things about your code.  The write
statement will in fact write 325 times, its just you only SEE the last
one because each time through the loop the call to open() inFile
obliterates the old file.

You can either move the infile = open... line outside the loop (on top),
open inFile in 'a' (append) mode, or form a new output filename for each
file.  My personal preference would be for the first option.

BTW two other comments:

1) Using 'inFile' for an output file is very confusing.

2) It's generally good practice to explicitly close files, even though
in Python you don't really have to.  Explicit closing helps document the
code and helps ensure that what you want to happen is indeed what is
happening.

Hope that helps.
