[[wikipedia:Python_(programming_language)|Python]] is a general-purpose, high-level programming language. It is also a type of snake, but one is arguably more suitable for behavioral research than the other.

On the lab computers, there is support for Spyder, PyCharm and [[Psychopy]].

==Installation==
==Upgrade from 2.7 to 3.7==
Since Python version 2.7 has reached end of life since January first 2020, this version is no longer installed on our [[System Image]]. Standard is now: Python 3.7 64-bits.
If you still have scripts written in Python2, the scripts should be upgraded to Python 3. Most changes are probably the print statements. Print statements should always have parentheses: print('some text')
Key differences between Python 2 and Python 3 are here: https://sebastianraschka.com/Articles/2014_python_2_3_key_diff.html
For our previous documentation for Python 2.7, see [[Python/Legacy]]
==Configuration==
==Psychopy==
{{see also|Psychopy}}
Psychopy 2020.2.10 has been installed in the root of the Python3.7 64-bit version. This is also the default version when 'psychopy' is typed from the command prompt. It is also the default that opens when a .py file is double-clicked. It also can be started by clicking the appropriate icon on the desktop.
There is also a Psychopy 2020.2.10 installed on Python3.6 32-bits. This version has its own icon on the desktop and should be used when you are using a [[Tobii Eye Tracker]].
[[image:python_env.jpg]]
When your script fails to load in Psychopy, because you need packages that are not installed on our lab computers, please contact TSG.
