PsychoPy is an open-source package for creating experiments in behavioral science. It aims to provide a single package that is:

* precise enough for psychophysics
* easy enough for teaching
* flexible enough for everything else
* able to run experiments in a local Python script or online in JavaScript

To meet these goals PsychoPy provides a choice of interface - you can use a
simple graphical user interface called Builder, or write your experiments in
Python code. The entire application and library are written in Python and is
platform independent.

There is a range of documentation at:

* [PsychoPy Homepage](https://www.psychopy.org)
* [Youtube](https://www.youtube.com/playlist?list=PLFB5A1BE51964D587)
* The textbook, [Building Experiments in PsychoPy](https://uk.sagepub.com/en-gb/eur/building-experiments-in-psychopy/book253480)
* [The discourse user forum](https://discourse.psychopy.org)
