Scientific Python (SciPy)—pronounced sigh pie—is a group of Python packages created for the scientific community. It contains many functions, including a wide range of random number generators, linear algebra routines, and optimizers. SciPy is a comprehensive package and, over time, people have developed many extensions to customize and extend the package according to their needs.

The following are the main packages that are part of this ecosystem:

• NumPy: For algorithms, the ability to create multi-dimensional data structures, such as arrays and matrices, is really important. NumPy offers a set of array and matrix data types that are important for statistics and data analysis. Details about NumPy can be found at http://www.numpy.org/.
• scikit-learn: This machine learning extension is one of the most popular extensions of SciPy. Scikit-learn provides a wide range of important machine learning algorithms, including classification, regression, clustering, and model validation. You can find more details about scikit-learn at http://scikit-learn.org/.
• pandas: pandas is an open source software library. It contains the tabular complex data structure that is used widely to input, output, and process tabular data in various algorithms. The pandas library contains many useful functions and it also offers highly optimized performance. More details about pandas can be found at http://pandas.pydata.org/.
• Matplotlib: Matplotlib provides tools to create powerful visualizations. Data can be presented as line plots, scatter plots, bar charts, histograms, pie charts, and so on. More information can be found at https://matplotlib.org/.
• Seaborn: Seaborn can be thought of as similar to the popular ggplot2 library in R. It is based on Matplotlib and offers an advanced interface for drawing brilliant statistical graphics. Further details can be found at https://seaborn.pydata.org/.
• iPython: iPython is an enhanced interactive console that is designed to facilitate the writing, testing, and debugging of Python code. 
• Running Python programs: An interactive mode of programming is useful for learning and experimenting with code. Python programs can be saved in a text file with the .py extension and that file can be run from the console.
