Python is a general-purpose high-level programming language with an emphasis on code readability and writing algorithms in fewer lines of code than other programming languages. Python is open-source and managed by the Python Software Foundation. It has an extensive standard library and can be extended with many external libraries including a rapidly growing set of scientific and mathematical libraries such as SciPy, NumPy and Sympy and an extensive plotting library Matplotlib. 20-sim scripting has been tested with the following versions of Python: Python 2.7.x, Python 3.4.x and Python 3.5.x (32-bit and 64-bit).
During installation of 20-sim, you are asked to install the (optional) Python 3.4 package. We advise to keep the default setting (Yes) which will install the Python 3.4 installation that includes 20-sim scripting support and the following packages: NumPy, Matplotlib and IPython. This installation provides just enough support to get started with 20-sim scripting. However, it does not provide a development IDE or an extensive set of scientific and mathematical libraries.
