Get ConfigObj to quote strings

If I run the following script:

from configobj import ConfigObj
 config = ConfigObj()
 config.filename = 'test.cfg'
 config['keyword1'] = "the value"
 config['keyword2'] = "'{0:s}'".format("the value")
 config['keyword3'] = '"{0:s}"'.format("the value")
 config.write()
 

the output is:

keyword1 = the value
 keyword2 = "'the value'"
 keyword3 = '"the value"'
 

Is there any way to produce the following output?

keyword1 = 'the value'
