- "[Jupyter](http://jupyter.org/) is an interactive browser based notebook environment where we can combine text, code execution and visualization. It supports multiple programming languages through it's language specific kernel plugins. However, it is widely used with Python in scientific computing and data science communities. The availability of large number of high quality open source libraries useful for many tasks in scientific computing,numerical linear algebra, machine learning and visualization ensures that Python is being widely used in these fields. Jupyter notebooks are an excellent environment for learning and teaching because of the interactivity.\n",
