   * Python is provided through the **[[habrok:software_environment:module_system|module system]]**, which gives you access to several different versions of Python as well as a number of pre-built, performance-optimised libraries. You should always start by loading a Python module rather than relying on any system Python.   * Python is provided through the **[[habrok:software_environment:module_system|module system]]**, which gives you access to several different versions of Python as well as a number of pre-built, performance-optimised libraries.
