Question

in python: how fix the code below so that the output will print out on decimal place? the rounding should be at the print area.

class Rectangle:
   """
       Rectangle class
   """
  
   def __init__(self, width=1, height=2):
       """
           Constructor

       # Initializing private variables

       self.__height = height;

       return self.__width;

main();

Explanation / Answer

Hi

I have fixed the issue and highlighted the code changes below

class Rectangle:
"""
Rectangle class
"""
  
def __init__(self, width=1, height=2):
"""
Constructor
"""
# Initializing private variables
self.__width = width;
self.__height = height;
  
def getWidth(self):
"""
Function that returns width of a rectangle
"""
return self.__width;
  
def getHeight(self):
"""
Function that returns height of a rectangle
"""
return self.__height;
  
def getArea(self):
"""
Function that returns area of a rectangle
"""
return self.__width * self.__height;
  
def getPerimeter(self):
"""
Function that returns perimeter of a rectangle
"""
return 2 * (self.__width + self.__height);
  
def main():
"""
Main function
"""
# Creating object
rect = Rectangle(4, 40);
  
# Printing data
print(" A " + str(rect.getWidth()) + " x " + str(rect.getHeight()) + " rectangle has an area of " + str(round(rect.getArea(),1)) + " and a perimeter of " + str(round(rect.getPerimeter(),1)) + ". ");
  
  
# Creating object
rect1 = Rectangle(3.5, 35.7);
  
# Printing data
print(" A " + str(rect1.getWidth()) + " x " + str(rect1.getHeight()) + " rectangle has an area of " + str(round(rect1.getArea(),1)) + " and a perimeter of " + str(round(rect1.getPerimeter(),1)) + ". ");
  
# Calling main function
main();

Output:

sh-4.3$ python3 main.py                                                                                                                                                                                                                                                

A 4 x 40 rectangle has an area of 160 and a perimeter of 88.                                                                                                                                                                                                          

A 3.5 x 35.7 rectangle has an area of 125.0 and a perimeter of 78.4.
