Python's seek() has an option to specify "relative to the end of file" for a file open in read mode. Old docs: <http://docs.python.org/2.4/lib/bltin-file-objects.html> Current docs: <http://docs.python.org/2/library/stdtypes.html#file-objects> There is also os.stat() <http://docs.python.org/2/library/os.html#files-and-directories> /dps -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
