Exercise 1

Write a class called MyString which has a function called "devowel" which returns the input string with no vowel

s = MyString("hello")
s.devowel() # returns "hll"
          

class Mystring:
    def __init__(self, string):
        self.string = string

    def devowel(self):
        strin = list(self.string)
        output = []
        vow = list('aeiou')
        for element in strin:
            if element not in vow:
                output.append(element)
        return print("".join(output))

Exercise 2

Write a class called Player which starts with 100 health has 2 functions, hit and heal which hit and heal the player for some specified value. Once the players health to 0 or less, print out "he ded"

p = Player()
p.hit(99)
p.heal(20)
p.hit(20)
p.hit(1) # prints out "he ded"
            

class Player:
    def __init__(self):
        self.health = 100

    def hit(self, number):
        self.health -= number
        if self.health <= 0:
            print('he ded')

    def heal(self, number):
        self.health += number

Exercise 3

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

 c = Circle(5)
c.perimeter() # prints out 2*pi*5
c.area() # prints out pi*5^2
              

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

    def perimeter(self):
        print(pi*2*self.radius)

    def Area(self):
        print(pi*self.radius*self.radius)

Exercise 4

Write 2 Python classs named Rectangle and Square, Rectangle should take in height and width and have a function to computer permeter and area. Square should inherit these functions from Rectangle and be constructed with just 1 paramater, x

 r = Rectangle(1,2)
r.area()      # 2
r.perimeter() # 6
s = Square(2)
s.perimeter() # 8
s.area()      # 4
                

class Rectangle:
    def __init__(self, height, width):
        self.height = height
        self.width = width

    def perimeter(self):
        print(2*(self.height+self.width))

    def area(self):
        print(self.height*self.width)

class Square(Rectangle):
    def __init__(self, height):
        super().__init__(height, height)
