finesse.constants¶
Physical constants module exposing a single named-tuple which contains each of the constants values.
This tuple is imported in the top-level Finesse module - allowing access to this structure with:
from finesse import constants
# get the speed of light for example
c = constants.C_LIGHT
The table below lists all of the constants exposed in this module.
| Name | Description | Exact value used | 
|---|---|---|
| C_LIGHT | The speed of light in m/s. | 299792458.0 | 
| PI | Mathematical constant \(\pi\). | 3.14159265358979323846 |
