Python's data science libraries can be broken down into three different categories:
- Data Mining
- Data Processing and Modeling
- Data Visualization

Categorizing Python Libraries for DS

Several Python libraries are commonly downloaded and used for the processing, visualization, and analysis of data. These include:

- **scikit-learn**: A machine learning library.
- **NumPy**: A library for scientific computing.
- **pandas**: A library for data manipulation and analysis.
- **Matplotlib**: A plotting library.

Core Python Libraries for Data Science

- **NumPy**: Used for array operations and scientific/data computing.
- **Pandas**: Used for data manipulation, cleaning, and analysis via dataframes.
- **Matplotlib**: A core plotting library offering multiple data visualization options.
- **Seaborn**: Built on Matplotlib, used for creating attractive statistical graphics like heatmaps.
- **BeautifulSoup**: Used for web crawling and scraping data from HTML/XML files.
- **SciPy**: An open-source scientific computing library covering statistics, integration, optimization, and image processing.
- **StatsModels**: Provides classes and functions for estimating and testing various statistical models.

Data Science Libraries Within Python

Python is a powerful language that allows data scientists to perform data manipulation, analysis, and visualizations through its vast number of libraries such as numpy and pandas.

University of Michigan - Ann Arbor

Python is an interpreted, object-oriented, high-level programming language. It's known for its built in data structures and robust libraries. Despite this, Python was developed to have an easy to learn syntax which emphasizes readability and whitespace. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and standard library are available without charge for all major platforms, and can be freely distributed.

Python Programming Advanced Topics

Python is an interpreted language, meaning that code written in the language is not converted into machine-readable code, but instead byte code. This byte code is then translated by an interpreter called the Python Virtual Machine whenever the program runs. On the fly, the interpreter translates the byte code into machine-readable into code that the CPU executes.

Interpretation

Python is an object-oriented programming language. OOP is a programming paradigm that provides a means of structuring programs so that properties and behaviors are bundled into individual objects. For instance, an object could represent a person with properties like a name, age, and address and behaviors such as walking, talking, breathing, and running. Object-oriented programming is an approach for modeling concrete, real-world things, like cars, as well as relations between things, like companies and employees, students and teachers, and so on. OOP models real-world entities as software objects that have some data associated with them and can perform certain functions.

Python as an Object Oriented Programming (OOP) Language

Imperative programming is a programming paradigm where computation is executed step-by-step as it is defined in the code. This approach makes it easier to design new machine learning models because developers can intuitively utilize standard control flow constructs (such as loops and conditionals) and tap into vast, existing software ecosystems, like that of Python. Additionally, imperative programming simplifies the debugging process, as developers can readily access and inspect all intermediate variable values during execution.

Imperative Programming

Conventionally, when evaluating deep neural networks, the Python interpreter must execute the code layer by layer to generate instructions that are then forwarded to a CPU or GPU. While this eager execution is fine for a single fast device, the single-threaded nature of the Python interpreter becomes a severe bottleneck when scaling to advanced multi-GPU servers (e.g., an 8-GPU instance). In such setups, Python struggles to generate instructions fast enough to keep all GPUs fully utilized. This bottleneck can be resolved by using hybrid programming to compile sequential models into optimized symbolic representations, thereby bypassing the Python interpreter during execution.
