Part 1Calculating Profit AmountThroughout this course, you will use the latest version of Python to develop programs. Python is a high-level, general-purpose language created in the early 1990’s that has become popular in business and academic applications. Python can be used for web application development, desktop application development, and massively multiplayer online role-playing games such as Eve Online. Python can be installed on different operating systems (Windows, Linux, Mac, etc.), and the free version can be installed from the Python official website at python.org.For this interactive assignment, you will take on the role of a Python programmer that is part of a team of programmers for an online sales company. The head of the accounting department told you that the company’s annual profit is typically 19 percent of the company’s total sales. He has tasked you to write a simple Python program that will calculate and display the estimated profit amount from an annual amount of sale. In this coding assignment you will utilize what you learned while reviewing the required resources for Week 1. Your program will have to display a clear message to prompt the user to enter any amount of sale (Total Sale: $xxxxx), and it should calculate the estimated profit amount, and show the result in the following format:Profit Amount: $xxxxxxOnce you have completed the program, take a screen shot of the completed functionality (including the input and the output) and save it in a Word document, along with the script.In your initial post,Attach your word document.Describe your process in developing the program. Part 2Python VariablesPrior to beginning this discussion read Chapter 2: Variables and Expressions in the course text.Python variables do not need explicit declaration to reserve memory space. Based on this statement, address the following in your initial post:Describe the difference between explicit typed variables and implicit typed variables using examples.In large scale applications, explain whether or not explicit declaration has a better impact over implicit declaration.

Modify an existing Java Web application that violates several Payment Card Industry guidelines and recommendations. Your task is to locate the issues, identify what is wrong and then fix the code. You will discuss each issue in terms of why the issue may cause a security vulnerability, and how you specifically fixed the issue. The current code, uses Java JSP and Servlets to allow a user to login to their account and view credit card data stored in the database. The functionality is relatively simple but several PCI compliance rules have been violated that will prevent the application from being approved by a PCI software auditor. You should first load up the application, populate the database and make sure the application is working in your environment as expected. The application uses the Java Derby relational database. The script used to populate the application is attached as well as the Java web project itself. You should be able to open the existing project using NetBeans. However; you may need to load the Derby drivers to the libraries for the project. Once you have the database loaded, you can try the application. (This assumes you have properly installed the Java EE when you installed NetBeans). Email:john.doe@test.edu Password: mypassword Review the code and perform analysis as needed. You should experiment with  application as well as reviewing the code to identify possible areas of security concerns. You don’t have to be an expert in JSP/Servlets, html or css to be able to find some of the issues that you have read about in the PCI documentation. However; it is recommended you experiment with the code so you have a baseline familiarity with the model and know how the JSP and servlets communicate with each other. Focus on the PCI compliance issues found in sections 6 through 9 (see attached jpg file) as you look for issues. There are multiple issues and you should work to fix and document as many as possible.Submission: Provide all of your modified Java code, your modified database script and a word document describing how you addressed each issue. You should clearly describe the code and what PCI compliance issue were violated and how you fixed it. You should provide screen captures as needed to support your findings and improvements.
