Answer 1

Ans:-

Output of the above program is:- Name: Hayden Age: 26 Roll Number: 6

Explaination:-

The above program is a python program which is implementing namedtuple class from collection. Namedtuple is like a dictionary which contains key and value. The values can be accessed using index or attribute or getattr() method.

In the above program we are using attribute to access the elements.Now, let us go through the lines of code

from collections import namedtuple # this will import the namedtuple from collections in the program

Student = namedtuple('Student' , ['name','age','rollNo']) # this will create student namedtuple where name, age and rollNo are attribute

student1 = Student('Hayden' , 26, 6) # this will add a new student

print
print ("Name:", student1.name) # this method print the name of student using name attribute
print

print ("Age:", student1.age) # this method print the age of student using age attribute
print

print ("Roll Number:", student1.rollNo) # this method print the roll no of student using rollNo attribute
print

So, in the above code, only three statements will be printed and this will be the output of the program, first is name of student using name attribute, second is age of student using age attribute and third is roll number of student using rollNo attribute. Hence, the output will be  Name: Hayden Age: 26 Roll Number: 6
