Study Notes
Popular Data Science Tools
- Python, R, Microsoft Excel, SAS, and SPSS are used for data pre-processing and analysis
- Tableau, Qlikview, and Microsoft Excel are used for data exploration and visualization
- Apache Spark and Apache Hadoop are used for parallel and distributed computing with big data
Evolution of Python
- Guido van Rossum developed Python in the late eighties at the 'National Research Institute for Mathematics and Computer Science' in the Netherlands
- Python's editions include Python 1.0, 2.0, and 3.0
Python as a Programming Language
- Supports multiple programming paradigms: Functional, Structural, and OOPs
- Uses dynamic typing, with runtime type safety checks
- Employs reference counts, deallocating unused objects
- Uses late binding, where methods are looked up by name during runtime
- Tim Peters' Zen of Python describes the 20 aphorisms that guide it's design
- The "Python Software Foundation" manages the Standard CPython interpreter
- Other interpreters include: JPython (Java), Iron Python (C#), Stackless Python (C, for parallelism), and PyPy (Python itself JIT compilation)
- Standard libraries are written in Python itself and maintains high standards of readability
- Python is cross-platform, meaning it's compatible across Windows, Linux, and Mac
- It has a large community group, providing high support and better error handling
- In comparison to Java, Java is statically typed, meaning type safety is checked during compilation (static compilation)
- Therefore, in Java the time required to develop the code is more
- Python, which is dynamically typed, compensates for huge compilation time compared to Java
- Dynamically typed codes tend to be less verbose, offering more readability
Advantages of Using Python
- Features make it well suited for data science
- It is open source and benefits from community development and it's Open Source Initiative license allows it to be used and distributed commercially for free
- Python has a simple syntax and is easy to understand
- Many libraries are designed for specific data science tasks
- It combines well with the majority of the cloud platform service providers
Coding Environment
- A software program can be written using a terminal, command prompt (cmd), a text editor or through an Integrated Development Environment (IDE)
- The program needs to be saved in a file with an appropriate extension, such as “.py” for Python or “.mat” for Matlab
- Then it can be executed in corresponding environment, i.e. Python, Matlab
- An Integrated Development Environment (IDE) is a software product solely developed to support software development in various or specific programming language(s)
- Python 2.x support was available until 2020
- Python 3.x is an enhanced version of 2.x maintained from 3.6.x post 2020
- It is recommended to install a basic python version or use the online python console
- Basic print statements, naming conventions, conditional operations, function declarations, and installing modules, should be executed to view the outputs
Integrated Development Environment (IDE)
- Software application made of a cohesive unit of tools required for development
- IDEs are designed to simplify software development
- Utilities include tools for managing, compiling, deploying, and debugging software
Coding Environment: IDE Features
- IDEs usually have a source code editor, compiler, and debugger
- Additional features include syntax and error highlighting and code completion
- Supports building and executing programs along with debugging
Coding Environment: IDE Examples
- Version control features are included in the best IDEs
- Popular general IDEs with Python support: Eclipse+PyDev, Sublime Text, Atom, GNU Emacs, Vi/Vim, Visual Studio, Visual Studio Code
- Python-specific editors: Pycharm, Jupyter, Spyder, Thonny
Spyder IDE
- Supported across Linux, Mac OS X, and Windows platforms
- Available as open-source
- Can be installed separately or through Anaconda distribution
- Specifically developed for Python and data science
- Features include a code editor with robust syntax and error highlighting, as well as code completion, navigation, a debugger, and integrated documents
- Interface is similar to MATLAB and RStudio
PyCharm IDE
- Compatible with Linux, Mac OS X, and Windows platforms
- Available as a community (free open source) and professional (paid) version
- Only supports Python
- Can be installed separately or through Anaconda distribution
- Features include a code editor with syntax and error highlighting, code completion, navigation, unit testing, debugger, and version control
Jupyter Notebook
- Web application for creation and manipulation of documents called 'notebooks'
- Supported across Linux, Mac OS X, and Windows platforms
- Available as open source
- Bundled with Anaconda distribution or can be installed separately
- Supports Julia, Python, R, and Scala
- Consists of an ordered collection of input and output cells that contain code, text, plots, etc
- Users can also share code and narrative text through output formats like PDF, HTML etc
- Jupyter Notebook is an education and presentation tool
- Jupyter Notebook lacks most of the features of a good IDE
How to Choose the Best IDE
- Requirements and working with different IDEs helps understand one's own requirements
