from their example, it's illegal to call

getvalue

after

close

, but the

content

saved by the earlier

getvalue

call should still be valid, that's what i read

# Retrieve file contents -- this will be
# 'First line.\nSecond line.\n'
contents = output.getvalue()

# Close object and discard memory buffer --
# .getvalue() will now raise an exception.
output.close()
