ii) the 16000$ restumping fee iii. Ihe $2000 tor the new hot water system. Where appropriate, support your answer with both legislative and case authority. Tara is an employee who owns a rental property which had a leaking roof and so needed repair. She arranged for a roof plumber to attend the property at 10:00am on a Wednesday. She also turned up at that time. She used her own key to allow entry for both herself and the plumber to the property. However, the tenant insisted that he had not given Tara permission to come at that time, and called the police, who charged Tara with trespass. Tara went to court and incurred $15 , 000 in legal fees. She was found not guilty. During the tax year, Tara also paid $16 , 000 to have the investment property restumped as the flooring was not level. The flooring had been uneven when she purchased the house 2 years ago, but as she had bought the property without visiting it she was not aware of this at the time. She also spent $2000 on a new hot water system for the investment property because the old one had recently broken down. .

I want to make this code in python using tkinter .. Develop a simple Mosques Management System considering the following: A. The system should be developed with a Graphical User Interface using TKinter This is a suggested structure of the interface The interface contains the following elements: - Part 1: input fields to allow the users to enter mosques data as follows: Part 2: A ListBox to display the data records Part 3: selection buttons to allow the user selecting the required operation Part 4: These are for the extra work that can be added (see below) B. It is required to build a class for the mosques and then create a mosque object for each entry C. The system should be connected to a database to contain mosques data in the Mosq table (use sqlite 3 library) Build a class for the database to include the following methods: Use the class to create a new database object and then use its methods for supporting all the operations of the system (displaying all the mosques records, searching for a record of a specific mosque, adding a new record for a mosque, deleting a record of a mosque) There are some extra features that you can incorporate into your system for additional marks: 1. Adding the Update operation: To enable the user to update the Imam_name field in the database. In this case, the user firstly searches for a mosque record by name and then uses the additional 'update' button (part 4) to apply the modification after modifying the field. 2. Adding the Display on Map operation: To enable displaying the location of the mosque on the map. In this case, the user first searches for a mosque record by name and then use the additional 'Display on Map' button (part 4) to display the location on the map using the coordinates information. Hint: use "folium" and "webbrowser" libraries. 3. Enhancing the search operation: In case the user enters a misspelled name, the system can provide the user with the very close matching names in the database. Then the user can select the correct name to search for. Hint: use "difflib" library. .
