4. Student NamedTuple

Write a Python program that defines a NamedTuple called Student with fields like name, age, and marks (a list of subjects and marks).

Sample Solution:

Code:

from collections import namedtuple

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

# Create an instance of the Student NamedTuple
student1 = Student("Svetovid Borko", 22, {"Math": 85, "Science": 90, "History": 78, "English": 92, "Art": 88})
student2 = Student("Mohan Balbino", 22, {"Math": 75, "Science": 82, "History": 95, "English": 88, "Art": 90})
student3 = Student("Tacita Jerzy", 21, {"Math": 92, "Science": 87, "History": 85, "English": 78, "Art": 91})

# Access and print fields using dot notation
print("Student 1:")
print("Name:", student1.name)
print("Age:", student1.age)
print("Marks:", student1.marks)

print("\nStudent 2:")
print("Name:", student2.name)
print("Age:", student2.age)
print("Marks:", student2.marks)

print("\nStudent 3:")
print("Name:", student3.name)
print("Age:", student3.age)
print("Marks:", student3.marks)

Output:

Student 1:
Name: Svetovid Borko
Age: 22
Marks: {'Math': 85, 'Science': 90, 'History': 78, 'English': 92, 'Art': 88}

Student 2:
Name: Mohan Balbino
Age: 22
Marks: {'Math': 75, 'Science': 82, 'History': 95, 'English': 88, 'Art': 90}

Student 3:
Name: Tacita Jerzy
Age: 21
Marks: {'Math': 92, 'Science': 87, 'History': 85, 'English': 78, 'Art': 91}

In the exercise above, we define a NamedTuple named "Student" with the fields 'name', 'age', and 'marks'. The 'marks' field contains a dictionary of subjects and their corresponding marks. Next "Student" NamedTuples are created with different student information, including names, ages, and marks. The fields of each student are then accessed and printed using dot notation.

• Write a Python program to define a NamedTuple `Student` with fields: name, age, and marks (a list of subjects and marks), then print each student's name along with their marks.
• Write a Python function that takes a list of `Student` NamedTuples and returns the student with the highest average mark.
• Write a Python script to filter a list of `Student` NamedTuples to only those whose average mark is above a given threshold, and then print their names.
• Write a Python program to sort a list of `Student` NamedTuples by age and then by name, printing the sorted order.
