Is there a python library with a rainbow color function?

What I want is a function such that I give as input a number between 0. and 1. and it returns a color on the rainbow palette between red and violet. In this way, if the input is np.linspace(0.,1.,7) it will return the seven colors of the rainbow in order.

    You can probably write one that does what you want. See my answers to the questions [Range values to pseudocolor](https://stackoverflow.com/questions/10901085/range-values-to-pseudocolor) and [Calculate RGB value for a range of values to create heat map](https://stackoverflow.com/questions/20792445/calculate-rgb-value-for-a-range-of-values-to-create-heat-map) for examples. – martineau Oct 10 '19 at 18:52
  • @martineau T.Y. I was hoping for an already existing function (in mathematica it exists), but I can also try to make it manually as you suggest. – 3sm1r Oct 10 '19 at 19:00

    3sm1r: I understand your question, however asking for recommendations is off-topic on this site — which is why suggested that you look at some related questions (and their answers). If you can't get your own function to work, then asking a question about that _would_ be something appropriate here. – martineau Oct 10 '19 at 19:05

Use pystyle

import pystyle
from pystyle import Colors, Colorate

print(Colorate.Horizontal(Colors.rainbow, 'some rainbow text'))

You can easily create a function that returns the value what you needed.
