You are going to enhance the prior assignment by doing the following:-

1) Create a function for each math operation (add, div, mult, sub)
2) The application will run forever, you will ask the user to continue or not.3) create a function IsinRange() to test a value between two ranges like this;Here is the spec in pseudocodeIsInRange(lr, hr, n) lr=low rangehr=high rangen=numberif n between ln and hnreturn trueelsereturn false

Hints 1) For practice please see lab exercises in the lesson section
2) See Sample output for messagesSample output

Enter your Lower range —> 10
Enter your Higher range —> 20
Enter your First number —> 15
Enter your Second number —> 17

The Result of 15.0+17.0=32.0
The Result of 15.0-17.0=-2.0
The Result of 15.0*17.0=255.0
The Result of 15.0/17.0=0.882352941176

Continue Looping Y/N Y

Enter your Lower range —> 20
Enter your Higher range —> 30
Enter your First number —> 25
Enter your Second number —> 50

      The input values are outside the input ranges
      Please check the numbers and try again

You are going to enhance the prior assignment by implementing exceptions

***** You need to tell me where you implemented the exception and why. *****Show me 2 test cases that will trap the errors. Your code needs to implement two separate try-except blocks for the appropriate area of the code. This means you cannot wrap your entire code with try-except blocks.
