Study Notes
Popular Tools Used in Data Science
- Data pre-processing and analysis tools include Python, R, Microsoft Excel, SAS, SPSS.
- For data exploration and visualization, Tableau, QlikView, and Microsoft Excel are commonly used.
- Apache Spark and Apache Hadoop are key technologies for parallel and distributed computing in big data contexts.
Evolution of Python
- Python was created by Guido van Rossum in the late 1980s at the National Research Institute for Mathematics and Computer Science in the Netherlands.
- Significant versions of Python include:
- Python 1.0
- Python 2.0 (supported until 2020)
- Python 3.0 (current version with ongoing support).
Python as a Programming Language
- Supports various programming paradigms including functional, structural, and object-oriented programming (OOP).
- Features dynamic typing, allowing type checks at runtime for increased flexibility.
- Utilizes reference counting to manage memory, deallocating unused objects.
- Late binding enables method resolution during runtime.
- Guided by the "Zen of Python" with 20 aphorisms emphasizing simplicity and readability.
Python Interpreters
- The standard CPython interpreter is maintained by the Python Software Foundation.
- Alternative interpreters include:
- Jython (integrates with Java)
- IronPython (integrates with C#)
- Stackless Python (enhanced parallelism)
- PyPy (Just-In-Time compilation for Python).
Advantages of Using Python
- Open-source under the Open Source Initiative license, allowing free use and distribution.
- Simple and readable syntax, making it accessible to various skill levels.
- Rich libraries tailored for data science applications.
- Compatible with numerous cloud service providers.
Coding Environment
- Software programs can be developed using terminals, command prompts, text editors, or Integrated Development Environments (IDEs).
- Python files should be saved with a .py extension for execution in appropriate environments.
- IDEs streamline the development process with specialized tools.
Integrated Development Environment (IDE)
- An IDE combines development tools like a source code editor, compiler, and debugger into a single application.
- Provides utilities for code management, compiling, deploying, and debugging.
IDE Components
- Key features of IDEs include:
- Source code editing
- Syntax and error highlighting
- Code completion and navigation
- Best IDEs offer version control features to manage code changes effectively.
Popular Python IDEs
- General IDEs that support Python include Eclipse with PyDev, Sublime Text, Atom, Visual Studio, and Visual Studio Code.
- Python-specific IDEs include PyCharm, Jupyter, Spyder, and Thonny.
Spyder
- A robust IDE designed for data science, compatible with Linux, Mac OS X, and Windows.
- Open-source version available; can be installed standalone or via Anaconda.
- Features include:
- Code editor with syntax highlighting
- Integrated debugging tools
- Document management similar to MATLAB and RStudio.
PyCharm
- An IDE exclusively for Python, available in community (free) and professional (paid) versions.
- Supports features such as syntax highlighting, code completion, unit testing, and debugging.
- Can be installed separately or through the Anaconda distribution.
Jupyter Notebook
- A web-based application for creating and manipulating documents called "notebooks."
- Supported across Linux, Mac OS X, and Windows platforms, and available as open-source.
- Can be bundled with Anaconda or installed independently.
- Supports multiple programming languages including Python, Julia, R, and Scala, features cells for input/output and documentation.
