Assignment Background
The 2019-nCoV is a newly discovered contagious virus that is causing respiratory infections. It is confirmed to be a zoonotic virus, meaning it can spread from person to person, and was first known to cause a human infection in December 2019. Any further information about the situation should only be acquired from trusted sources such as the CDC.Project Description
This project focuses on analyzing a publicly available dataset containing information about the spread of nCoV. Since this is an active situation, this dataset is constantly being updated with the latest figures. However, for our purposes, we will use a static version of the dataset provided to you with this project (Another file (ncov_small.csvncov.csv)). This static version was lasted updated on March was last updated February 5th. 18th.open_file() -> fp
This function takes no parameters and returns a file pointer to the data file. You likely have a copy from a previous project. It repeatedly prompts for a file until one is successfully opened. It should have a try-except statement. By default (when the user does not provide a filename), this function opens the file ncov.csv.build_dictionary(fp) -> dictionary
This function accepts the previously generated file pointer as input and returns the required dictionary. You have to use csv.reader to read the data file since the area name has a comma. This function iterates over the CSV reader and within each iteration, extracts the needed data and then creates a dictionary that holds all of the data. Remember to skip the header line. Also, the order of countries and areas in the dictionary will be the same as the order observed in the CSV file. This dictionary is then returned by the function. The data to be extracted is: Country column 3 Area column 2 Last update column 4 Cases column 5 Deaths column 6 Recovered column 7 The structure of the dictionary is as follows: {country: [{area : (last_update, cases, deaths, recovered)},]} The dictionary contains a list of dictionaries. Each dictionary within the list has the key as the area within the country and value as a tuple. This tuple contains last updated date, numbers of cases, number of deaths, and number of recovered respectively. For example:| 1 | Area | Country/Region | Last Update | Confirmed | Deaths | Recovered |
| 54 | Chicago, IL | US | 2/1/2020 19:43 | 2 | 0 | 0 |
| 55 | San Benito, CA | US | 2/3/2020 3:53 | 2 | 0 | 0 |
| 56 | Santa Clara, CA | US | 2/3/2020 0:43 | 2 | 0 | 0 |
| 67 | Boston, MA | US | 2/1/2020 19:43 | 1 | 0 | 0 |
| 68 | Los Angeles, CA | US | 2/1/2020 19:53 | 1 | 0 | 0 |
| 69 | Orange, CA | US | 2/1/2020 19:53 | 1 | 0 | 0 |
| 70 | Seattle, WA | US | 2/1/2020 19:43 | 1 | 0 | 0 |
| 71 | Tempe, AZ | US | 2/1/2020 19:43 | 1 | 0 | 0 |
top_affected_by_numbers(dictionary) -> list
This function accepts the data dictionary and produces a sorted list of the top 10 countries with the most total people affected within every country. This is similar to the previous function, except that instead of counting the total areas affected, we are counting the total people affected in each country. For these counts, we use the numbers in the cases column. The returned sorted list (in descending order) will contain key-value pairs such that each key is a country and the corresponding value is the number of cases observed within that country. For example, in the case of Australia and Malaysia, the tuple will be as follows: [(Australia, 13),(Malaysia: 10)]affected_states_in_country(dictionary, string) -> set
This function takes in the data dictionary and the name of a country (string) and returns a set of affected areas within a country (if you are curious, the function name contains the word states which is what we started with but changed descriptions to be areas as new data came inthe function name wasnt changed). The function should return an empty set if the user enters a non-existent country name. The string representing the country may be any mixture of cases, e.g. China is equivalent to cHiNa which is equivalent to chiNA etc.is_affected(dictionary, string) -> Boolean
This function takes in the data dictionary and the name of a country (string) and returns a Boolean (True or False) depending on whether a country is affected by nCoV. A country is affected by nCoV, if it is in the dictionary. The string representing the country may be any mixture of cases, e.g. China is equivalent to cHiNa which is equivalent to chiNA etc.plot_by_numbers(list, list) -> plot
This function is provided. You do not need to modify the source code for this function. However, you do need to invoke this function at the appropriate place. This function accepts a list of countries and a list of numbers corresponding to those countries and generates a graph using this data.main()
Begin by opening the file and building the master_dictionary by calling the appropriate functions. The main function prints the provided BANNER and MENU and then asks the user to make a choice between the various available options shown in the menu. If the user inputs something other than an integer, print an error message and reprompt. If the choice is 1, the program compiles a list of countries with the most (top) areas affected by calling the appropriate function and then displays the results to the user in descending order. Use the following string formatting: {:<20s} {:5d} It then asks the user if they want to plot the results. Depending on users response, plot can be displayed. Plot only the top 5 countries and their corresponding area counts. Make a list of countries and a list of their counts to use as arguments to the plotting function. If the choice is 2, the program compiles a list of countries with the most people affected by calling the appropriate function and then displays the results to the user in descending order. Use the following string formatting: {:<20s} {:5d} It then asks the user if they want to plot the results. Depending on users response, plot can be displayed. While plotting, plot the 5 most affected countries starting from the 2nd most affected country. That is ignore the top, most-affected country. The graph becomes difficult to visualize otherwise with a high concentration of infections in Mainland China (at the time we collected the data). If the choice is 3, the program prompts for a country, compiles a list of areas affected within that country (from the set returned by affected_states_in_country ) and displays the names of areas affected in alphabetic order along with counters such as [01] and [02]. Use the following string formatting: [{:02d}] {:<30s} If the choice is 4, the user is asked to input the name of a country. The program will display one of two strings depending on whether the country is affected. Check the strings.txt file to obtain these strings. Note: the program needs to catch exceptions in all the input sequences. For example, if the choice is not 1,2,3,4 or 5, then an error message is displayed, and user is asked for input again. Similarly, for country name in choice 3, if the user enters an invalid country name then an error message is displayed.Assignment Deliverables
The deliverable for this assignment is the following file: proj09.py the source code for your Python program Be sure to use the specified file name and to submit it for grading via the Mimir before the project deadline.Assignment Notes
- Use itemgetter() from the operator module to specify the key for sorting.
- Items 1-9 of the Coding Standard will be enforced for this project.
Suggested Procedure
- Solve the problem using pencil and paper first. You cannot write a program until you have figured out how to solve the problem. This first step is best done collaboratively with another student. However, once the discussion turns to Python specifics and the subsequent writing of Python statements, you must work on your own.
- Write a simple version of the program. Run the program and track down any errors.
- Use the debugger available in Spyder to locate and resolve errors. Set breakpoints right before the instructions where you perceive the program begins and then step through the code one instruction at a time. While doing this, keep an eye on the variable explorer window in Spyder to observe the change in variables.
- Use the Mimir system to turn in the first version of your program.
- Cycle through the steps to incrementally develop your program:
- Edit your program to add new capabilities.
- Run the program and fix any errors.
- Use the Mimir system to submit your final version.
- Be sure to log out when you leave the room, if youre working in a public lab.
