2. Use some if statements to add three filters to your program that let the user select exactly one state, disease and year to include in the report. Prompt the user to enter these values. Introduction This assignment lets you practice with reading from a file and manipulating lists. Preparation Enter state: Colorado Enter disease: shallpax Enter year: 1928 State Disease Number Year This assignment must be done in a standalone Python environment, not the textbook.

Make sure that you get output like this before starting the assignment or writing any additional code. Your program should run as expected using this small data set Directions Modify the program in the following ways: 1. Write each line as part of a table, include a header before the table, and a summary line at the end. Use a fixed width for each column (don't try to find the largest width like you did in the previous unit). You should end up with something like 4. Change the open statement in the program to use the full data set, health-no-head.csv. 5. Write down the answers to the following queries: 1. How many cases of Hepatitis A were reported in Utah in 2001? 2. How many cases of polio have been reported in California? 3. How many cases of all diseases were reported in 1956? 6. Add another feature to your program. This could be something like printing the highest and lowest numbers for each query or allowing the user to just type the first part of value, so that entering 20 for the year generates a table for years 2000, 2001, 2002, ... 2011, or entering D for a state gives information on Delaware and the District of Columbia. Or maybe leverage your previous assignment and make the column only as wide as they need to be for the data.
