Get from a Task the display value of a specific custom field in python

Yes sure, with the code client.tasks.get_tasks_for_project(project_gid , opt_fields=(‘gid’,‘name’,‘custom_fields.display_value’)) I can take all the display value of the custom fields I have in the project. To take the display value of just one, let say the display value of the custom field that have the gid value of ‘120000000400’, how could I do it?
