practical-01 Data Management: SQL+web-server

Find the min, max, sum, and average of the marks in a student marks table.
Find the total number of customers from each country in the table (customer ID, customer Name, country) using group by.
Write a SQL query to order the (student ID, marks) table in descending order of the marks.
Integrate SQL with Python by importing MYSQL dB
Write a Django based web server to parse a user request (POST), and write it to a CSV file.

practical-02 Data handling using Python libraries

Use map functions to convert all negative numbers in a Data Frame to the mean of all the numbers.
Consider a Data Frame, where each row contains the item category, item name, and expenditure.
Group the rows by the category, and print the total expenditure per category.
Given a Series, print all the elements that are above the 75th percentile.
Given a day’s worth of stock market data, aggregate it. Print the highest, lowest, and closing prices of each stock.
Given sample data, plot a linear regression line.
Take data from government web sites, aggregate and summarize it. Then plot it using different plotting functions of the PyPlot library.

practical-03 Basic Software Engineering

Business use-case diagrams for an airline ticket booking system, train reservation system, stock exchange
Collaboratively write a program and manage the code with a version control system (GIT)

05 Project

The aim of the class project is to create something that is tangible and useful. This should be done in groups of 2 to 3 students and should be started by students at least 6 months before the submission deadline. The aim here is to find a real world problem that is worthwhile to solve. Students are encouraged to visit local businesses and ask them about the problems that they are facing. For example, if a business is finding it hard to create invoices for filing GST claims, then students can do a project that takes the raw data (list of transactions), groups the transactions by category, accounts for the GST tax rates, and creates invoices in the appropriate format. Students can be extremely creative here. They can use a wide variety of Python libraries to create user-friendly applications such as games, software for their school, software for their disabled fellow students, and mobile applications, Of course to do some of this projects, some additional learning is required; this should be encouraged. Students should know how to teach themselves.

If three people work on a project for 6 months, at least 500 lines of code is expected. The committee has also been made aware about the degree of plagiarism in such projects. Teachers should take a very strict look at this situation, and take very strict disciplinary action against students who are cheating on lab assignments, or projects, or using pirated software to do the same. Everything that is proposed can be achieved using absolutely free, and legitimate open source software.
