Python is a general-purpose, high-level programming language. It is also a type of snake and a rollercoaster, but one is arguably more relevant to your research than the others.
On the lab computers, there is support for Spyder, PyCharm and Psychopy.

Installed version3.7.9 64-bits
Development statusActive

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:

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.

When your script fails to load in Psychopy, because you need packages that are not installed on our lab computers, please contact TSG.



Execute the following script within the commandline (CMD): python a.
You should see the following result:

number of argument:  2
 argv[0]: ./
 argv[1]: a
