Hi everyone 👋! In this video I demonstrated 40 tips to help you become more proficient in day-to-day data science tools such as Jupyter notebooks, VS Code, Python, R and RStudio, and Excel! It's definitely the longest video I have ever made and took me tons of time, but hopefully it will give you some useful tips, no matter if you are a novice or a seasoned data analyst/ data scientist.
Thank you for watching and have a great day! 🤗
