Show how to define a view tot_credits (year, num_credits), giving the total number of credits taken by students in each year
andreev551 [17]

Hi! I'm a Digital Marketer Intern at hotels.ng and I have a moderate knowledge on programming.

First, your  question is not very explanatory. The term "view" is often used in back-end web development. A view is simply a Python function that takes a Web request and returns a Web response.

But I'm not sure this is what you want, so I'll just go ahead and write a python function involving class to return the total number of credits taken by a student.

I'll answer this question using Python.

class student(object):  

    credits = None

    year = None

    def num_credits(self):


       #get credit value

       self.credits = input("Enter the total number of credits: "  )


       pass

    def getYear(self):

        self.year = input("Enter current year: ")

        pass

    def tot_credits(self):

          TotalCredits = tempTotalCredits + self.num_credits

           print "Your  total credits are :"+" "+str(TotalCredits)

Marta_Voda [28]

Answer and Explanation:

Messages flow across an SDN controller's:  

Northbound APIs:  

• Messages which help in read/write state of the network and developing flow tables within the  

state management layer.  

• Notifications for the state-change events.  

• The interaction between the controller and network control applications is done through the  

northbound interface.  

• Network control applications send messages to the controller.  

Southbound APIs:  

• Messages which help for the up-to-date view of the network's state like message for the  

attached link has gone up or down, new devices are joined the network, or indications of the  

device is up or down.  

• Controller's southbound interface is the communication among the controller and the controlled  

devices. Controlled devices are the recipients of the messages sent form the controller.
