Introduction

In this paper, I will demonstrate my understanding and execution of the skills outlined in the assignment prompt. The focus will be on developing a self-contained Python module, using string methods, connecting to web services, reading and understanding specifications, employing proper docstring conventions, adhering to coding standards, and performing comprehensive testing.

Development of the Python Module

To start, I designed a self-contained Python module that performs a specific task—fetching data from a web API and processing string information. The module includes functions with clear preconditions, thorough docstrings, and adheres to the course's coding conventions. For example, one function, fetch_data(), connects to a public web API to retrieve JSON data. It includes exception handling to manage network errors, verifying preconditions such as valid URL format and internet connectivity. The function's purpose and assumptions are documented via docstrings according to standards.

The module is organized into sections with helper functions to process strings using methods like .strip(), .lower(), and .replace(). These operations demonstrate proficiency with string methods. Comments within the code cover the logic and intended use of each function, facilitating understanding and maintenance.

Connecting Python to a Web Service

In implementing the web connection, I used the requests library—a standard approach in Python. The function validates inputs, performs the GET request, and processes the response. Proper error handling ensures robustness. This demonstrates understanding of how to establish a client-server connection and handle data returned in JSON format.

Reading Specifications and Using Docstrings

Throughout development, I carefully read and interpreted the specifications provided. The use of docstrings follows the format recommended in the course, clearly stating function purpose, parameters, return values, preconditions, and postconditions. This practice facilitates both comprehension and testing.

Following Coding Conventions and Testing

My code adheres to the course’s coding standards, including consistent indentation, meaningful variable names, and modular design. To ensure correctness, I wrote multiple test cases covering typical, boundary, and error scenarios. For example, tests confirm correct data processing, proper error handling, and behavior with invalid inputs.

Conclusion

This assignment provided an opportunity to apply fundamental Python practices and software engineering principles. By constructing self-contained modules, connecting to web services, and emphasizing testing and readability, I have reinforced my skills crucial for effective programming and software development.
