TRIANGLE: 

Scenario

Now we're going to embed the Point class (see Lab 3.4.1.14 i.e points on a plane) inside another class. Also, we're going to put three points into one class, which will let us define a triangle. How can we do it?

The new class will be called Triangle and this is the list of our expectations:

  • the constructor accepts three arguments - all of them are objects of the Point class;
  • the points are stored inside the object as a private list;
  • the class provides a parameterless method called perimeter(), which calculates the perimeter of the triangle described by the three points; the perimeter is a sum of all legs' lengths (we mention it for the record, although we are sure that you know it perfectly yourself.)

Complete the template we've provided in the editor. Run your code and check whether the evaluated perimeter is the same as ours.

Expected output

3.414213562373095


CODE:

import math



class Point:

    def _init_(self, x=0.0, y=0.0):

        self.__x = x

        self.__y = y


    def getx(self):

        return self.__x


    def gety(self):

        return self.__y


    def distance_from_xy(self, x, y):

        return math.hypot(abs(self._x - x), abs(self._y - y))


    def distance_from_point(self, point):

        return self.distance_from_xy(point.getx(), point.__y)#

    # The code copied from the prev lab



class Triangle:

    def _init_(self, vertice1, vertice2, vertice3):

        self.__list=[vertice1,vertice2,vertice3]#

        


    def perimeter(self):

a=self._list[0].distance_from_point(self.list[1])+self.list[0].distance_from_point(self.list[2])+self.list[1].distance_from_point(self._list[2])

        return a# Write code here

        #CISCO:

#def perimeter(self):

  #      per = 0

    #    for i in range(3):

      #      per += self._vertices[i].distance_from_point(self._vertices[(i + 1) % 3])

        #return per



triangle = Triangle(Point(0, 0), Point(1, 0), Point(0, 1))

print(triangle.perimeter())

20. Valid Parentheses Easy 18.3K 1K Companies Given a string  s  containing just the characters  '(' ,  ')' ,  '{' ,  '}' ,  '['  and  ']' , determine if the input string is valid. An input string is valid if: Open brackets must be closed by the same type of brackets. Open brackets must be closed in the correct order. Every close bracket has a corresponding open bracket of the same type.   Example 1: Input: s = "()" Output: true Example 2: Input: s = "()[]{}" Output: true Example 3: Input: s = "(]" Output: false   Constraints: 1 <= s.length <= 10 4 s  consists of parentheses only  '()[]{}' . My code: class Solution: def isValid(self, s: str) -> bool: a='([{' b=')]}' c=[] for i in s: if i in a and s.count(i)!=s.count(b[a.find(i)]):#checks if no.of opening element==no of closing element print(i,b[...
