Write a class calculator to perform addition and subtraction. Create 3 calculator objects with different input values of your choice in your program. These 3 objects should be able to perform both addition and subtraction of inputted values. Using python OOP.

Please do it in python I have asked this question before but i need it in try and except  You have been asked to take a small icon that appears on the screen of a smart telephone and scale it up so it looks bigger on a regular computer screen. The icon will be encoded as characters (x and *) in a 3 x 3 grid as follows: Write a program that accepts a positive integer scaling factor and outputs the scaled icon. A scaling factor of k means that each character is replaced by a k ? k grid consisting only of that character. Input Specification: (Use a try and except here)The input will be an integer such that 0 < k ≤ 10. Output Specification:The output will be 3k lines, which represent each individual line scaled by a factor of k and repeated k times. A line is scaled by a factor of k by replacing each character in the line with k copies of the character. Use try and except
