In the "Python Basics" course, I gained a solid foundation in Python 3 programming, learning to write and run simple programs while exploring essential concepts such as control structures, including conditional execution and iteration. I developed a strong understanding of key data structures like strings and lists, honing my skills in manipulating and analyzing them to solve practical problems. The course also introduced me to Turtle graphics, allowing me to creatively draw shapes and designs through programming. I improved my debugging skills by using reference diagrams to visualize program execution and implemented iteration and accumulation patterns to process data effectively. Additionally, I explored boolean data types and various forms of conditionals, which enhanced my ability to control program flow.

In the "Python Functions, Files, and Dictionaries" course, I learned how to effectively incorporate files into my Python programs, enabling me to read and write data from various formats, including CSV. I explored the mechanics of dictionaries, practicing how to build and manipulate them using accumulation patterns. The course also introduced me to function construction, where I learned how to define functions, use parameters, and manage variable scope. Additionally, I gained insight into iteration mechanisms, particularly while loops, and advanced function concepts like optional parameters and anonymous functions with lambda. Finally, I developed sorting techniques for Python objects and completed a project that involved analyzing social media post sentiments using the skills I acquired throughout the course.

In the course "Data Collection and Processing with Python," I gained essential skills for fetching and processing data from online services. I learned to work with complex data structures, particularly focusing on processing JSON formatted data and traversing nested data using nested iterations. This understanding allowed me to extract values from complex, deeply nested data effectively. I also explored advanced accumulation techniques, using the map and filter functions, along with list comprehensions, to transform and filter data efficiently. A significant portion of the course was dedicated to using the Python requests module to interact with Application Programming Interfaces (APIs), enabling me to request and cache data from various sources. For the final project, I applied these skills to construct a "tag recommender" for the Flickr photo-sharing site, integrating all I had learned about data retrieval and processing in Python.

In the course "Python Classes and Inheritance," I gained a solid foundation in object-oriented programming concepts, focusing on the creation and utilization of classes and instances in Python. I learned how to design custom classes that encapsulate both data and functionality, allowing for clearer and more maintainable code structures. The course emphasized the importance of class inheritance, enabling me to reuse code effectively by creating subclasses that extend the functionality of existing classes. I also delved into the process of overriding built-in methods, which enhanced my understanding of customizing class behavior. Furthermore, I was introduced to exception handling and unit testing, where I learned to write automated test cases to ensure my code operates as expected.

In the "Python Project: Software Engineering and Image Manipulation" course, I've gained practical experience in utilizing third-party APIs and working with the Python Imaging Library (Pillow) to manipulate images. I learned to apply optical character recognition (OCR) techniques using Tesseract and the Py-Tesseract library, enabling me to extract text from images effectively. This hands-on project not only enhanced my programming skills in Python but also allowed me to create a real-world data-analysis project that is suitable for showcasing in a portfolio. The course emphasized software engineering principles, laying a strong foundation for my understanding of how to approach data-driven projects.
