A program is needed for a swimming club to manage the annual naudit of its membership details.

The data stored about each member includes name, age, gender, type of membership, whether

a team member or not, annual fee and if the fee has been paid. Team members are allowed a

discount of $10\%$ on their annual membership fee.

The types of membership available are:

Membership Age range in years Annual fee

junior $>=2$ and $<18$ $$10\mathrm{.}00$

adult $>=18$ and $<50$ $$20\mathrm{.}00$

senior $>=50$ and $<80$ $$15\mathrm{.}00$

golden $80$ and over free

Write Python code and test a program or programs for the swimming club annual audit:

$$ Your program or programs must include appropriate prompts for the entry of data.

Data must be validated on entry.

$$ All outputs, including error messages, need to be set out clearly and understandably.

$$ All variables, constants and other identifiers must have meaningful names.

You will need to complete these three tasks. Each task must be fully tested.

Task $1$ setting up the system to store the membership details

Set up your program to:

$$ store the members$$ details in arrays

$$ populate the arrays with at least $20$ members$$ details

$$ use the array index as the annual membership number.

Task $2$ providing annual audit statistics

Count the number of current members by membership type. For each type of membership count the

number of members who did not pay the annual fee. Display these counts as a percentage of the

total number of members for each membership type. Calculate and display the total of the annual

fees expected and the annual fees received for this year.

Task $3$ updating the membership details for the next year

Extend your program to:

$$ check if any members have not paid and output a list of all these members

$$ remove these members from the system

$$ update the age of all the members by one year and whether they are in a team

$$ update the type of membership and the annual fee if required

$$ set the fee for every member as not yet paid

$$ display lists of current team members grouped by membership type.
