Question
Please use Python
Write the code for an application to convert and display a (decimal) number in binary and
hexadecimal notation: (see image resource 1)
Note that the binary and hexadecimal equivalents should be displayed as LCD numbers. Hint:
Use the QLCDNumber class.
If the user enters an invalid integer, an error message like the following should be displayed: (see image resource 2)
Similarly, if there is an overflow in the number of digits displayed for the binary representation,
an appropriate error message should be displayed.
Use signals and slots to connect the various buttons to the appropriate functions.
Submit the code of all classes that you write, as well as the main program that creates and
shows the GUI window. Submit images of the application while it is running to show that it works
as required.

- Finding nearby cells with offsets Sometimes you want to calculate things based upon cells close by to the cell you are providing a calculation in. OFFSET() retrieves the values in cells offset from the current location by a certain number of rows and columns. It takes two arguments: the number of rows down to move from the current location, and the number of columns to move right. You can also specify height and width arguments to return a range of cells, which is often useful in combination with a summary statistic function like SUM(), AVERAGE() or MAX(). Instructions In cell I1, get the count of Skippers in the Indian Subcontinent as the value from the cell offset 1 down from C1. In cell I2, again get the count of Skippers in the Indian Subcontinent, this time as the value from the cell offset 2 right from A2. In cell I3, get the count of Skippers in Western Himalaya as the values from the range of cells offset 2 right from A3, with height 7, and sum them.

The oval should automatically resize and reposition itself when the window is resized. In this activity you will start with our OvalDraw application in our sample code, review the code, and then make incremental improvements to the application. Be sure to make the resulting application uniquely your own by adding standard comments at the top application (i.e. your name, class, etc.), changing the names of variables, and adding small features. Finally, be sure to save your work as you will often be asked to submit it as part of an assignment. Be sure to review the example OvalDraw project in the Java section of our example code repository.
