$1.$ The World Health Organization $($WHO$)$ compiles data about immunization levels around the world to support global health initiatives, including Sustainable Development Goal $3($SDG $3)$: Good Health and Well$-$being. This goal emphasizes the importance of universal access to healthcare services, including vaccines. The file named $$measles$.$txt$$ contains data on measles vaccination levels in various countries, contributing to the global effort to end the measles epidemic. Each line of the file contains the following fields, separated by a space:

$$ Country $(50$ characters$)$: Name of the country.

$$ Income Level $(6$ characters$)$: Category assigned by the World Bank, with possible values being WB$\_$LI $($low income$),$ WB$\_$LMI $($lower middle income$),$ WB$\_$UMI $($upper middle income$),$ and WB$\_$HI $($high income$).$

$$ Percent Vaccinated $(3$ characters$)$: Percentage of the population vaccinated against measles from age one.

$$ Region $(25$ characters$)$: Region assigned to that country by WHO.

$$ Year $(4$ characters$)$: The year the data was collected.

$2.$ You will develop two Python programs as described below to process and analyze this data, aiding in the assessment and advancement of SDG $3$ by providing insights into global immunization trends. Each program will be in a separate source code file, as detailed under $$Assignment Deliverables$.$

$3.$ Your programs may use any built$-$in or library functions.

$3\mathrm{.}1$ Part A

$1.$ The program in $$GCS$182\_$PRJ$\_$A$.$py$$ will copy selected lines from $$measles$.$txt$$ into a file selected by the user.

a$)$ The program will always read from $$measles$.$txt$($it will not prompt the user for the name of the input file$).$ If it is unable to open that file, the program will stop.

b$)$ The program will prompt the user for the name of the output file. If that file does not exist, the program will create it and continue. If that file already exists, the program will discard the current contents of the file and continue.

c$)$ The program will prompt the user to enter a year and will copy all lines of $$measles$.$txt$$ selected by the user$$s response. A line is selected if the user$$s response matches the Year field or any of its prefixes. All lines are selected if the user$$s response is any of the values in the set $\{,$all$,$ALL$\}.$ Note that $$ is the empty string.

For example, a line whose Year field contains $1987$ would be selected by any of the following user responses: $\{1,19,198,1987,,$all$,$ALL$\}.$

$2.$ The output file created by the program will have the same format as the input file $($same field widths and spacing$).$ Note that when the user selects all lines, the output file will be identical to the input file.

$3.$ The program will display appropriate messages to inform the user about any unusual circumstances.

$3\mathrm{.}2$ Part B

$1.$ The program in $$GCS$182\_$PRJ$\_.$py$$ will display one summary report to the user.

a$)$ The program will prompt the user to enter the name of the input file. If it is unable to open that file, the program will prompt the user again until the user enters a valid file name.

b$)$ The program will prompt the user to enter a year and will then prompt the user to enter an income level. The income level must be one of the characters in the set $\{1,2,3,4\},$ where $1$ corresponds to $$low income$,2$ corresponds to $$lower middle income$,3$ corresponds to $$upper middle income$$ and $4$ corresponds to $$high income$.$

c$)$ The program will identify all records $($lines$)$ in the input file which match the user$$s criteria for year and income level, and the program will display a report with the following information:

$$ The count of records in the input file which match the user$$s criteria

$$ The average percentage for those records $($displayed with one fractional digit$)$

$$ The country with the lowest percentage for those records

$$ The country with the highest percentage for those records

The name of the country and the percent of children vaccinated will be displayed for the last two items $($lowest percentage and highest percentage$).$

$2.$ The program will display appropriate messages to inform the user about any unusual circumstances.

$3.$ The program will contain at least three functions.

$4.$ SUBMISSION
