    "- As a general purpose language, Python may not be the best tool for any particular job, but it is generally the second best tool for everything. This is useful since a data science project may include everything from scraping data from the web, analyzing a mixture or text and numerical data, computing features, training a model, creating high-quality graphs, and then hosting a website with your results. \n",

    "- Python is explicitly and by design, user-friendly. Python is built to be human-interpretable, making it easier to work with. \n",

    "- Python also has a massive user community doing similar things, which is useful because this community creates a large number of tools you can use. The best language for your project is one which has the things you need.\n",

    "Python3 was a break from Python2, because there were some larger changes that broke [backwards compatibility](https://en.wikipedia.org/wiki/Backward_compatibility). Many still use Python2 - for a while, Python3 had fewer available tools, since it takes a while to update large codebases. Now though, Python3 has pretty much everything available, and is the future of Python. In practice, Python 2 & 3 are quite similar - learning one will be mostly relevant for knowing the other, and code can usually be made compatible between both with minimal changes.\n",
