Assignment Instructions

This assignment involves constructing Python programs that use basic data structures such

lists, searching and sorting as well as file IO to manipulate data.

The assignment has one question that involves the use of functions to implement the following

data structures; lists, searching and sorting, as well the file IO techniques as we have seen in

Assignment $10.$ Some of your methods will specifically be tested individually by the automarker

so make sure that you follow instructions carefully in each case.

NOTE Your solutions to this assignment will be evaluated for correctness and for the following

qualities:

Documentation

Use of comments at the top of your code to identify program purpose, author and

date.

Use of comments within your code to explain each non$-$obvious functional unit of

code.

General style$/$readability

The use of meaningful names for variables and functions.

Algorithmic qualities

Efficiency, simplicity

These criteria will be manually assessed by a tutor and commented upon. In this assignment, up to

$10$ marks will be deducted for deficiencies.

Today, the most common way of keeping in touch with other colleagues, family and friends is through

digital communications. Many people use the contacts app on their phones, tablets or computers. In

this assignment, we will be implementing a simple contact manager to store, process and retrieve a

person's names, contact number, and email address. This information will be stored in a file, and we

will be employing the concepts we have learned from file input and output in this case.

NOTE: The automatic marker will test each of your functions individually. To enable this, you MUST
