1. I have been working with Python for five years. One project I worked on was a web scraping application that scraped data from multiple websites and stored it in a database using Python libraries like Beautiful Soup and Requests. 2. In Python, errors can be handled using try-except blocks. If there is an error in my code, I first try to identify the source of the problem by looking at the error message. Then, I try to reproduce the error in a smaller code snippet to understand the issue better. Once the issue is identified, I can either fix the code or add more try-except blocks to handle the error more gracefully. 3. A tuple is an immutable data type in Python, whereas a list is mutable. This means that once a tuple is created, its elements cannot be modified, whereas a list can be modified. Additionally, a tuple is represented using parentheses, while a list is represented using square brackets. 4. A decorator in Python is a function that takes another function as an argument and extends its functionality without modifying the original function. One example of a decorator is the @staticmethod decorator, which is used to define a static method inside a class. 5. In my Python projects, I use pip for dependency management. Pip is a package installer for Python modules and is used to install, upgrade, and remove packages from the Python Package Index (PyPI). I also use virtual environments to manage dependencies for different projects to avoid conflicts between dependencies.
