Kaggle is a platform for doing and sharing data science. You may have heard about some of their competitions, which often have cash prizes. It’s also a great place to practice data science and learn from the community. What are Kaggle Kernels? Kaggle Kernels are essentially Jupyter notebooks in the browser that can be run right before your eyes, all free of charge! Let me say that again in case you missed it, because this is quite amazing: Kaggle Kernels is a free platform to run Jupyter notebooks in the browser! This means you can save yourself the hassle of setting up a local environment, and have a Jupyter notebook environment inside your browser, anywhere in the world you have an internet connection.
