The prompt

After typing “relax” within a terminal you will be presented with

[numbers=none]
relax>

This is the Python prompt which has been tailored specifically for relax. You will hence have full access, if desired, to the power of the Python programming language to manipulate your data. You can for instance type

[numbers=none]
relax> print("Hello World")

the result being

[numbers=none]
relax> print("Hello World")
Hello World
relax>

Or using relax as a calculator

[numbers=none]
relax> (1.0 + (2 * 3))/10
0.69999999999999996
relax>
