When you do a reply on the digest, delete all the parts that aren't

The standard library has no module called argument. If you want to
import a module, you need to write it, and save it to a file with a .py
extension. Or perhaps you've installed such a module from some internet
site.

The standard way to open a file is with the built-in open() function.
Otherwise your syntax is missing the quotes around the r and w. To open
a text file, use:

infile = open("xxxx", "r")
outfile = open("yyyy", "w")

Again, assuming the data is text.
