This is what I've got so far:

import sys
myfiles = sys.argv[1:]
for i in zip(open(myfiles[0]), open(myfiles[1]), open(myfiles[2])):
    print " ".join(i)

How would you:

1.  zip an arbitrary number of files in this manner?  I hard-coded it
to do only three.
2.  Strip out trailing spaces and line breaks from the lines in each file?
