## 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):

def area(self):

def perimeter(self):

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

Sample Output:

```200.96
50.24
```

## 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)
```
