how to use modlist?

[<tn...@it...>]

Sorry for my stupid question but the document on ldap.modlist is not 
clear and no example.
I've tried to use function addModlist like below
ldap.modlist.addModlist(['key','value'])
and receive the error
...
AttributeError: 'list' object has no attribute 'keys'

Could you give me a small example to use modlist correctly.
Thanks.
