You just need to inherit the object and override that method you want to.

class StockMove(models.Model):
    _inherit = 'stock.move'

    @api.multi
    def _action_cancel(self):
        # Your code goes here
        return super(StockMove, self)._action_cancel()

i did't want all the function to override completely i just want to change a single line of code that defined in the parent class function

This way you can override the function, write your code. You need to call the super before / after your code.

If you want to change the existing line in the method, in this can you need to overwrite the whole method in your module and then change the code accrodingly.
