pi, c

[Louis Dumortier]

Hi all,


When importing numpy, some interesting constants are available :

>>> from numpy import pi
>>> pi
3.141592653589793
>>>



But did you ever wonder (like I do) why the speed of light is not known as
a constant ?






We use a handy package for this (and others).

Please have a look at : http://rhodesmill.org/pyephem/




Hope this is helpful.




Louis

Hi Louis,
To get the speed of light I use:

import scipy.constants.codata as cst

cst.c !
