worksheet3.write('A1', 'Sheet2 is hidden')

# Note, you can't hide the the "active" worksheet, which generally is the
# first worksheet, since this would cause an Excel error. So, in order to hide
# the first sheet you will need to activate another worksheet:
#
#    worksheet2.activate()
#    worksheet1.hide()

workbook.close()

Add minor clarification to hide_sheet example.
