Python Project Assignment

Project Detail Budget is fixed. Bid only if you do this project in this budget. 1. The first thing the program should do is try to open “[login to view URL]” in read mode, then load the data from the file into a variable named data and then close the file. ▪ The data in the file should be in JSON format, so you will need to use the “load()” function from the “json” module to read the data into your program. See the previous page for details of the data. ▪ If any exceptions occur (due to the file not existing, or it not containing valid JSON data), then simply set the data variable to be an empty list. 2. The program should then print a welcome message and enter an endless loop which starts by printing a list of options: “Choose [a]dd, [l]ist, [s]earch, [v]iew, [d]elete or [q]uit.” and then prompts the user to enter their choice. Once a choice has been entered, use an “if/elif” to respond appropriately (detailed below). 3. If the user enters “a” (add), prompt them to enter the setup and punchline of a joke, and use them to create a new dictionary with the structure shown on the previous page. Append the dictionary to the data list, then write the list to the text file in JSON format to save the joke. ▪ Use your “inputSomething()” function (detailed below) when prompting for the setup and punchline, to ensure that the user is re-prompted until they enter something. ▪ The dictionary for the new joke should contain 4 keys – “setup” and “punchline” should contain what the user entered, and “numOfRatings” and “sumOfRatings” should be given values of 0. ▪ Once the joke has been added to the data list, call your “saveChanges()” function (detailed below) to write the changes to the text file. 4. If the user enters “l” (list), display a list of the jokes (just the setup) preceded by their index number in the data list, or a “No jokes saved” error message if there is nothing in the list. ▪ Use a “for” loop to iterate through the jokes in the data list. ▪ You can use the “enumerate()” function to make sure you have a variable containing the index number of each joke as you loop through them (see Lecture 3). 5. If the user enters “s” (search), prompt for a search term and then list the jokes whose setup or punchline contains the search term. Remember to include the index number next to each result. ▪ This is a good opportunity to reuse and tweak the code used to list all jokes – the loop body needs an “if” to only print jokes that contain the search term (use the “in” operator – see Lecture 3). ▪ Convert the search term, joke setup and punchline to lowercase to find matches regardless of case. ▪ Use your “inputSomething()” function (detailed below) when prompting for the search term, to ensure that the user is re-prompted until they enter something. 6. If the user enters “v” (view), prompt them for an index number and then print the corresponding joke’s setup and punchline, including details of the joke’s rating. ▪ If the joke’s “numOfRatings” key contains a 0, show a “Joke has not been rated” message. Otherwise, show how many times the joke has been rated and the average rating of the joke (rounded to 1 decimal place), e.g. “Rated 3 time(s). Average rating is 3.3/5.” ▪ Use your “inputInt()” function (detailed below) when prompting for an index number, to ensure that the user is re-prompted until they enter an integer. ▪ Display an “Invalid index number” message if the user enters an index number that doesn’t exist in the data list. Also consider showing a “No jokes saved” message and not allowing the user to specify an index number if the data list is empty. This is not full description of project. Text for full description. Knowledge of tkinter is must for this.
