In this homework, you will use TKinter library in Python 2 to build a graphical user interface. The following are required: GUI look good with all the functionalities required. (1. Input window for user code input. 2. Output window for results output. 3. Next line button that reads the next line of input, and print this line to the output box. 4. A number showing which line your lexer is processing. 5. Clear labels so that user can understand how to use your program GUI.)

The final result would look like the following graph. However, you DO NOT need to create a GUl that looks exact like this. As long as you have the place for some source code, the place for output, a next button to read in next row of text from the source code and print this row on the output window, and a quit button to exit, you can design the interface appearance the way you like.
