This is a gentle introduction on scripting in Orange. Orange is a Python library, and the tutorial is a guide through Orange scripting in this language.
We here assume you have already downloaded and installed Orange and have a working version of Python. Python scripts can run in a terminal window, integrated environments like PyCharm and PythonWin, or shells like iPython. Whichever environment you are using, try now to import Orange. Below, we used a Python shell:
% python >>> import Orange >>> Orange.version.version '2.6a2.dev-a55510d' >>>
If this leaves no error and warning, Orange and Python are properly installed and you are ready to continue with this Tutorial.
