6. Student Average Grade

Write a Python function that takes a Student named tuple as an argument and calculates the average grade.

Sample Solution:

Code:

from collections import namedtuple

# Define a NamedTuple named 'Student' with fields 'name', 'age', and 'marks'
Student = namedtuple("Student", ["name", "age", "marks"])

def calculate_average_grade(student):
    total_marks = sum(student.marks)
    average_grade = total_marks / len(student.marks)
    return average_grade

# Create an instance of the Student NamedTuple
student1 = Student(name="Ain Ruth", age=22, marks=[89, 92, 75, 90, 86])

# Calculate and print the average grade for the student
average_grade = calculate_average_grade(student1)
print("Average Grade:", average_grade)

Output:

Average Grade: 86.4

In the exercise above, we declare a "Student" NamedTuple with the fields 'name', 'age', and 'marks'. The "calculate_average_grade()" function takes a "Student" NamedTuple as input, calculates the average grade from the 'marks' field, and returns it. Next, we create an instance of the "Student" NamedTuple and calculate and print the average grade.

• Write a Python function that takes a `Student` NamedTuple with a list of marks and returns the average mark, handling empty marks lists by returning None.
• Write a Python program to calculate the average grade of each student in a list of `Student` NamedTuples and print the names of students with an average above a given value.
• Write a Python script to compute the overall average mark for a class using a list of `Student` NamedTuples and then print the result.
• Write a Python function to compare two `Student` NamedTuples by their average marks and return the student with the higher average.
