Consider the class definition below. import math class Circle: a class to contain circles der _init__(self, xc, you, -1): he initiaire our circle with user inputs un self.x = x self.y - y self.radius or def_str_(self): return "X(), y(), radius (".format(self,x, self.y, self.radius) def circunference(self): w returns the circunference of the circle return math.pi. 2. self.radius def area(self): return math.pi.self.radius +2 def diameter(self): returns the diameter of the circle return 2. self.radius det inCircle(self, xp, yp): *** determines if point xp, yp is in the circle dmath.sqrt(xp - self.x)--2(yp - self.y)--2) if d < self.radius: return True else: return false What will print to the terminal if I run the following code: x = Circle(5) print(x) O <_main_Circle object at 0x7f9bc80647f0> Ox=0, y = 0, radius = 5 Ox=5, y =5, radius = 5 OX= 5, y = 0, radius = 1

Consider the class definition below: import math class Circle: a class to contain circles det init__(self, xc=, yc=8, r=1): an initialize our circle with user inputs self.x = XC self.y = ye self. radius - r def _str_(self): return "x = 0, y = {}, radius = {}".format(self.x, self.y, self.radius) def circumference(self): returns the circumference of the circle" return math.pi * 2 * self.radius def area(self): return math.pi * self.radius**2 def diameter(self): *** returns the diameter of the circle" return 2 * self.radius def inCircle(self, xp, yp): determines if point xp, yp is in the circle". d = math.sqrt((xp - self.x)**2 + (yp - self.y)**2) if d < self.radius: return True else: return false Explain the purpose of the lines in triple quotation marks at the beginning of each method and class definition. How is something in triple quotes different from a line starting with a hashtag symbol?

Consider the class definition below: import math class Circle: una class to contain circles def _init__(self, xc=®, yc=8, r=1): initialize our circle with user inputs self.x - XC self.y = yc self.radius - r def __str_(self): return "X = {}, y = {}, radius = {}".format(self.x, self.y, self.radius) def circumference(self): returns the circumference of the circle" return math.pi 2 * self.radius def area(self): return math.pi = self.radius**2 def diameter(self): returns the diameter of the circle" return 2 * self.radius def inCircle(self, xp, yp): determines if point xp, yp is in the circle d = math.sqrt((xp - self.x)**2 + (yp - self.y)**2) it d < self.radius: return True else: return false What is the purpose of the "self" argument in each method? Why is it necessary? If I create a circle assigned to the variable x, and then call x.diameter(), why do I not need to put anything in those parentheses?
