Python: A class constructed by a radius and two methods which will compute the area and the perimeter of a circle

Python Class: Exercise-11 with Solution

Write a Python class named Circle constructed by a radius and two methods which will compute the area and the perimeter of a circle.

Sample Solution:

Python Code:

class Circle():
    def __init__(self, r):
        self.radius = r

    def area(self):
        return self.radius**2*3.14
    
    def perimeter(self):
        return 2*self.radius*3.14

NewCircle = Circle(8)
print(NewCircle.area())
print(NewCircle.perimeter())

Sample Output:

200.96

Python: Tips of the Day

The Zip() Function:

>>> students = ('John', 'Mary', 'Mike')
>>> ages = (15, 17, 16)
>>> scores = (90, 88, 82, 17, 14)
>>> for student, age, score in zip(students, ages, scores):
...     print(f'{student}, age: {age}, score: {score}')
... 
John, age: 15, score: 90
Mary, age: 17, score: 88
Mike, age: 16, score: 82
>>> zipped = zip(students, ages, scores)
>>> a, b, c = zip(*zipped)
>>> print(b)
(15, 17, 16)
