Sagot :
Answer:
Following are the code to this question:
class Point:#defining a class Point
def __init__(self, x, y):#defining a constructor that takes three parameters
self.x = x#use self to hold x variable value
self.y = y#use self to hold y variable value
def Reflect_x(self):#defining a method reflect_x that hold object self
return Point(self.x, (-1) * self.y)#use return keyword that return positive x and negative y value
def __str__(self):#Use __str__ to convert object value into string
return "Point(" + str(self.x) + "," + str(self.y) + ")"#return string value
py = Point(3, 5)#defining a variable py that call class by passing the value
reflect = py.Reflect_x();#Use variable reflect to hold Reflect_x value
print("P:", py)#print value
print("Reflection about x axis of p:", reflect)#print value
Output:
P: Point(3,5)
Reflection about x axis of p: Point(3,-5)
Explanation:
In the code, a class "Point" is declared, inside the class, a constructor is created that hold three-parameter "self, x, and y", and use a self to hold x and y values.
In the next step, a "Reflect_x" method is defined that uses a class object and converts the x and y values, and in the next step, the str method is used that converts an object value into a string and return its values.
Outside the class, a py variable is defined, that holds Point values and pass into the Reflect_x method, and prints its return values.
