1. Choosing a Python Distribution
Given the popularity of the python language, there are many distributions. Each distribution is created for specific purposes:
- Standard distribution: it is the most used distribution especially for a beginner user. It is available for free download via the official site: www.python.org/download
- Pyschool: As the name suggests, PySchool is a free and open source Python distribution created primarily to meet the needs of students learning Python and data analysis, but it can also be used by scientists, engineers and data scientists. Pyschool includes more than 150 Python packages (full edition) including numpy, pandas, scipy, sympy, keras, scikit-learn, matplotlib, seaborn, beautifulsoup4...
- Anaconda: Anaconda and Miniconda: Anaconda is a complete Python distribution which contains a very powerful package manager named conda. Anaconda installs many packages and tools but requires several gigabytes of disk space. Miniconda is a lighter version of Anaconda, therefore faster to install and occupying less space on the hard disk. The conda package manager is also present in Miniconda.
- EduPython: free Python development environment allowing a quick start, which simplifies programming in Python for students and beginners.
- WinPython: A portable, no-installation, free open source distribution of the Python programming language for Windows XP/7/8/10. WinPython encompasses many science libraries designed for students of science subjects.
