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)

Explanation:
Data values in a program are held in variables. Variables are like containers for holding different types of data. A variable can be identified depending on the kind of data it holds. Variables can hold data types of integers, strings, arrays, lists, sets, Boolean etc. They hold unique data types and a can not hold different data types. Different rules exist for naming variables in different programming languages. A variable name should start with lowercase letters and be descriptive of the data it holds.
