Assignment 1 Stock Management The goal here is to write some software that would assist a retail store manage their stock levels. The assignment will get progressively more complex as it proceeds - the early stages will be reasonable straight forward and will be sufficient for a passing grade, and the more advanced stages are for those who wish to go further and target a higher overall result. General Requirements All assignments should be written in Python 3 and should run in IDLE. They can be written on any type of computer, but they should be able to be executed in the computer pool. The highest marks will be for working code. However, in cases where there are problems, you will be assigned marks for how you approached the task. It is also expected that you will provide comments in the programs to explain how it works, and these comments will account for up to 10% of the overall grade. In each case example output is given. You should try and make your output and process match the example as closely as possible. Stage 1: Data Entry Write a program which requests that requests a product name and a stock number. Store that data in a List or a Dictionary. After the user has entered data, request that the user enters Y or N to continue. If they enter N, print the list of products and stock numbers to the screen. If they enter Y, repeat the first step. Your program should produce the following result: *************************      Stock Manager ************************* Product Name: Widgets Stock Level: 14 Widgets has been entered with a stock of 14 products. Do you wish to enter another record? (Y/N) Y Product Name: Fidgets Stock Level: 22 Fidgets has been entered with a stock of 22 products. Do you wish to enter another record?

You need to: · Ensure that a stock number and product name were entered, If any of these were not entered, do not record that item and go straight to asking if they wish to continue. · Ensure that the user enters either "Y", "y", "N" or "n" when asked if they wish to continue. Continue to ask until they enter a valid result. · Ensure that the stock number is a number · Output the total number of products held in stock Sample output: *************************      Stock Manager ************************* Product Name: Widgets Stock Level: 12 Widgets has been entered with a stock of 12 products.

1. Assignment 1
Stock Management
The goal here is to write some software that would assist a
retail store manage their stock levels. The assignment will get
progressively more complex as it proceeds - the early stages
will be reasonable straight forward and will be sufficient for a
passing grade, and the more advanced stages are for those who
wish to go further and target a higher overall result.
General Requirements
All assignments should be written in Python 3 and should run in
IDLE. They can be written on any type of computer, but they
should be able to be executed in the computer pool.
The highest marks will be for working code. However, in cases
where there are problems, you will be assigned marks for how
you approached the task. It is also expected that you will
provide comments in the programs to explain how it works, and
these comments will account for up to 10% of the overall grade.
In each case example output is given. You should try and make
your output and process match the example as closely as
possible.
Stage 1: Data Entry
Write a program which requests that requests a product
name and a stock number. Store that data in a List or
a Dictionary. After the user has entered data, request that the
user enters Y or N to continue. If they enter N, print the list of
products and stock numbers to the screen. If they enter Y,
repeat the first step.
Your program should produce the following result:
*************************
Stock Manager
*************************
Product Name: Widgets
Stock Level: 14

2. Widgets has been entered with a stock of 14 products.
Do you wish to enter another record? (Y/N) Y
Product Name: Fidgets
Stock Level: 22
Fidgets has been entered with a stock of 22 products.
Do you wish to enter another record? (Y/N) N
-------------------------
Product Stock
-------------------------
Widgets 14
Fidgets 22
-------------------------
Stage 2: Validation and Totals
Building on stage 1, you now need to ensure that the program
checks for valid entries in each case, and converts the text to
the appropriate format.
You need to:
· Ensure that a stock number and product name were entered, If
any of these were not entered, do not record that item and go
straight to asking if they wish to continue.
· Ensure that the user enters either "Y", "y", "N" or "n" when
asked if they wish to continue. Continue to ask until they enter
a valid result.
· Ensure that the stock number is a number
· Output the total number of products held in stock
Sample output:
*************************
Stock Manager
*************************
Product Name: Widgets
Stock Level: 12
Widgets has been entered with a stock of 12 products.

3. Do you wish to enter another record? (Y/N)
Do you wish to enter another record? (Y/N) d
Do you wish to enter another record? (Y/N) y
Product Name:
Do you wish to enter another record? (Y/N) Y
Product Name: Fidgets
Stock Level: Twenty
Do you wish to enter another record? (Y/N) Y
Product Name: Fidgets
Stock Level: 20
Fidgets has been entered with a stock of 20 products.
Do you wish to enter another record? (Y/N) n

-------------------------
Widgets 12
Fidgets 20
-------------------------
Total 32
-------------------------
Stage 3: Product List and Menu
This involves three separate jobs:
· Create a menu with multiple options
· Add products separately and allow the user to select the
product.
· Allow multiple stock numbers to be entered for each product
and record the total

Stage 4: Importing, Exporting and Reporting
In the final stage we introduce the ability to load product lists,
export stock levels, and compare stock levels with expected
stock levels to generate a report. You will be provided with a
sample file for stock and a sample file to compare against.
This will require additional research into Python
Now that things are getting more complex, you are expected to
use functions to manage these tasks in your program.
