Python: Count the number of students of individual class

Python Collections: Exercise-33 with Solution

Write a Python program to count the number of students in an individual class.

Sample Solution:

Python Code:

# Import the Counter class from the collections module
from collections import Counter

# Create a tuple 'classes' containing class names and the number of students in each class
classes = (
    ('V', 1),
    ('VI', 1),
    ('V', 2),
    ('VI', 2),
    ('VI', 3),
    ('VII', 1),
)

# Create a Counter object 'students' to count the occurrences of class names in 'classes'
students = Counter(class_name for class_name, no_students in classes)

# Print the 'students' Counter object, which represents the count of students in each class
print(students) 

Sample Output:

Counter({'VI': 3, 'V': 2, 'VII': 1})
