Certainly. During my academic projects, I primarily worked with PHP and JavaScript, but I have also explored Python for personal projects. One project involved using Python for data analysis, where I utilized libraries like NumPy and Pandas to handle and analyze datasets. A challenge I encountered was optimizing the performance of my code when dealing with large datasets. To overcome this, I focused on writing more efficient code and leveraging the built-in functions of these libraries, which significantly improved processing speed. This experience enhanced my problem-solving skills and deepened my understanding of Python's capabilities.
