Answer

The scenarios are when;

• The spring input is invalid

• The source is not attached to the search engine in use

Explanation

A collection of saved data, organized for easy retrieval is called a database. Each data item is stored in a position relative to the others. A proper retrieval requires searching sequentially through the whole file record using a proper search word.

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)
