Week 7 Deliverables Overviewin This Week You Have Studied Additional

This week, you have studied additional Python language syntax for adding Image, Table, and Form HTML tags through functions and using the Python Flask module. The lab demonstrates your understanding of this functionality. Complete the assignment by developing and testing your Python code in the AWS Cloud9 IDE provided for the class, following the examples in the textbook and utilizing associated libraries, functions, and processes. Ensure adherence to the PEP Python Style guide, including limiting lines to 79 characters, placing imports at the top of the file after module comments, and using 4 spaces for indentation.

The submission requires two files: a Python script for the enhanced web page and a PDF or Word document showing your test results and documentation. The project, worth 80 points, involves enhancing the web page created last week with additional features, specifically with images, a table, and a form using Python Flask. The web page must include the basic HTML structure, including the page title and content, along with the new components.

Additional requirements include: at least four local images stored on the Cloud9 IDE environment, a table with at least four rows and three columns, and a form allowing user input with two text fields, one textarea, and a dropdown select component. The form should include submit and reset buttons, use POST as the action type, and send submitted data to a Cloud9 output file. The content and topics of the images, table, and form are flexible, but should be relevant and meaningful. Testing should verify all functionalities—from input to output—within the AWS Cloud9 environment. Document your process by including screenshots of the running application, both within Cloud9 and in the browser, demonstrating successful deployment and usage.

Start early, test thoroughly, and seek assistance if needed. Follow all submission instructions carefully to avoid academic integrity violations.

Introduction

The integration of Python with HTML to develop dynamic web pages is a fundamental skill in modern web development. Leveraging Python’s Flask framework facilitates creating web applications that include images, tables, and forms, which are essential components of interactive websites. In this paper, we detail the process of enhancing a basic web page by incorporating these elements, utilizing AWS Cloud9 as the development environment, and adhering to best practices in coding and documentation.

Utilizing Flask to Create Dynamic Web Content

Flask, a lightweight Python web framework, enables the development of web applications with minimal complexity. It allows embedding HTML components within Python scripts through templates or direct string rendering. To include images, tables, and forms, the Flask app must serve HTML pages with the desired elements dynamically generated or statically embedded. The Flask route decorator maps URLs to functions that return the HTML content, facilitating interaction between the server and client browsers.

Adding Images to the Web Page

The assignment requires including at least four images stored locally within the Cloud9 environment. These images can be anything relevant to the user’s interest or the page’s topic. To reference local images, they must be placed in the project directory and linked using relative URLs within the HTML Week 7 Deliverables Overview: This Week You Have Studied Ad tags. For example: <img src="images/pic1.jpg" alt="Sample Image">. Proper file organization ensures these images load correctly when accessed via the web server.

In the Flask application, static file handling is managed through the 'static' folder. The images should be stored within a subdirectory named 'static/images' to adhere to Flask's conventions. This setup ensures that the server correctly serves these media assets to clients, enhancing page visual appeal.

Creating and Populating a Table

An HTML table with at least four rows and three columns is added to present data effectively. The table can contain any data relevant to the web page's theme. Proper use of table headers (

) and data cells () enhances readability. The table is embedded directly within the HTML content served by Flask or generated dynamically depending on data source needs.

Sample table code:

<table border="1">


<tr>


<th>Header 1</th>


<th>Header 2</th>


<th>Header 3</th>


</tr>


<tr>


<td>Row 1, Cell 1</td>


<td>Row 1, Cell 2</td>


<td>Row 1, Cell 3</td>


</tr>


<tr>


<td>Row 2, Cell 1</td>


<td>Row 2, Cell 2</td>


<td>Row 2, Cell 3</td>


</tr>


<tr>


<td>Row 3, Cell 1</td>


<td>Row 3, Cell 2</td>


<td>Row 3, Cell 3</td>


</tr>


<tr>


<td>Row 4, Cell 1</td>


<td>Row 4, Cell 2</td>


<td>Row 4, Cell 3</td>


</tr>


</table>

Implementing a User Input Form

The web page includes a form allowing user input for two text fields, one textarea, and one dropdown select menu. The form uses method="POST" and submits data to the Flask server, which then writes the input to an output file stored on the server. The form includes submit and reset buttons for user interaction.

Sample form code:

<form method="POST" action="/submit">


<label for="name">Name:</label>


<input type="text" id="name" name="name"><br>


<label for="email">Email:</label>


<input type="text" id="email" name="email"><br>


<label for="comments">Comments:</label>


<textarea id="comments" name="comments"></textarea><br>


<label for="choice">Choose an option:</label>


<select id="choice" name="choice">


<option value="Option1">Option 1</option>


<option value="Option2">Option 2</option>


<option value="Option3">Option 3</option>


</select><br>


<button type="submit">Submit</button>


<button type="reset">Reset</button>


</form>

Upon submission, Flask handles the form data, writes it to a designated output file, and confirms receipt to the user.

Testing and Documentation

Thorough testing of all functionalities within the AWS Cloud9 environment ensures the web page operates as intended. This involves checking image loads, correct display of the table, proper form submission and reset behavior, and server response handling. Screen captures should document the application's operation both within the Cloud9 IDE and in the web browser, illustrating successful deployment and user interaction.

Documentation should include descriptions of the code structure, the static files organization, and the testing procedures. It should demonstrate understanding of client-server interactions, Flask routing, and static asset management.

Conclusion

Enhancing a web page with images, tables, and forms via Python Flask demonstrates critical web development skills, emphasizing static content management, dynamic content generation, and user input handling. Using AWS Cloud9 offers a scalable environment for such development, allowing real-time testing and deployment. Strict adherence to coding standards, thorough testing, and comprehensive documentation ensure a robust and professional web application.
