Variable length Argument

Suppose you want to print a list of student currently enrolled in a school for a class. In this we have to pass a list of student in this function.

def PrintStudentNames(SchoolName,classname,*b):
    print(SchoolName)
    print(classname)
    print("Student Names are as: ")
    for name in b:
        print(name)

So when we want to call N number of student from the function we may call it using:

PrintStudentNames(‘Army School’,’12 th class’,’Mohit’,’Raj’,’Shobhit’,’Ranjan’,’Mitra’,’Rajni’)

Output:

Army School
12 th class
Student Names are as: 
Mohit
Raj
Shobhit
Ranjan
Mitra
Rajni

Now try to write a programme that will help in  testing N number of test cases of addition..

so first write a addition programme.

def Add(a,b):
    return a+b

def Testing(*b):
    for i in b:
        print(i)
        varsum=Add(i[0],i[1])
        print("Summation is ",varsum)

#Now Test a programme:

Testing([1,2],[3,4],[7,8])

Now write a testing programme:

Output:

[1, 2]
Summation is  3
[3, 4]
Summation is  7
[7, 8]
Summation is  15
