Can anyone help me understand a part of the code in this Triangle Class?

Question

New to coding and have a question. There is a part of this code that I don't understand and am wondering if anyone can clarify. The code works as it should but I do not understand this one piece. What is this part of the code doing?

filledTrue = (filled == 1)

I am guessing it is passing filledTrue to the Superclass if filled equals 1, but I have not seen code used like this yet so am not sure. Do the parentheses work like an If statement without the Else component?

Thanks so much!

Here is the full code:

class GeometricObject:
    def __init__(self, color =  "green" , filled = True):
        self.__color = color
        self.__filled = filled

    def getColor(self):
        return self.__color

    def setColor(self, color):
        self.__color = color

    def isFilled(self):
        return self.__filled

    def setFilled(self, filled):
        self.__filled = filled

    def __str__(self):
        return  "color: "  + self.__color + \
             " and filled: "  + str(self.__filled)


class Triangle(GeometricObject):
    def __init__(self, side1 = 1.0 , side2 = 1.0, side3 = 1.0):
        super().__init__()
        self.__side1 = side1
        self.__side2 = side2
        self.__side3 = side3

    def getSide1(self):
        return self.__side1

    def setSide1(self, side1):
        self.__side1 = side1

    def getSide2(self):
        return self.__side2

    def setSide2(self, side2):
        self.__side2 = side2

    def getSide3(self):
        return self.__side3

    def setSide3(self, side3):
        self.__side3 = side3

    def setArea(self):
        self.area = area

    def getArea(self):
        s = (self.__side1 + self.__side2 + self.__side3) / 2
        area = (s * (s - self.__side1) * (s - self.__side2) * (s - self.__side3)) ** 0.5
        return area

    def getPerimeter(self):
        perimeter = self.__side1 + self.__side2 + self.__side3
        return  perimeter

    def triangleString(self):
        return "Triangle: Side 1: " + self.__side1 + "Side 2: " + self.__side2 + "Side 3: " + self.__side3

def main():
    side1 = eval(input("Enter a number for side 1: "))
    side2 = eval(input("Enter a number for side 2: "))
    side3 = eval(input("Enter a number for side 3: "))
    color = input("Enter a color for the triangle: ")
    filled = eval(input("To fill the triangle, enter 1, otherwise enter 0: "))
    filledTrue = (filled == 1)
    #set the variables in the classes
    triangleSolution = Triangle(side1, side2, side3)  # this sets the triangle sides in Triangle Class
    triangleSolution.setColor(color)  # this sets the color in the superclass (through subclass)
    triangleSolution.setFilled(filledTrue) # this sets the fill
    #get the variables in the classes with printout
    print("The triangle’s area is: ", triangleSolution.getArea(), '\n',
          "The perimeter is: ", triangleSolution.getPerimeter(), '\n',
          "The color is: ", triangleSolution.getColor(), '\n',
          "The color is filled: ", triangleSolution.isFilled())

main()

Variables assigned to a comparator x == y or others (greater than, less than, etc) will take a value of a boolean ( True or False ):

x = 1==1 # True
y = 'a'=='b' # False
z = 2 <= 5 # True
