1. PyData is a community for users and developers of open-source data tools in Python including NumPy, Pandas, SciPy, scikit-learn, IPython, and Jupyter. 2. Pandas is a software library written for data manipulation and analysis in Python, built on top of NumPy and SciPy. It provides data structures and operations for working with relational or labeled data and time series. 3. Jupyter Notebook is an open-source web application that allows users to create and share documents that contain live code, equations, visualizations and explanatory text. It supports over 40 programming languages including Python, R and Julia.
