Python problem with COPY - Mailing list pgsql-interfaces

#!/usr/bin/python

import pg

conn = pg.connect(dbname='mypython', host='localhost', user='hs')

conn.putline('COPY "income" FROM stdin')
conn.putline('name      22      1243')
# conn.putline('\.')
conn.endcopy()


Does anybody know why the script above does nothing?
