remove italics in latex subscript in matplotlib

Question

I would like to remove the italics font that appears when I use subscripts in labels. For example, the "Teff" in the x-label has "eff" in italics. I would like latex not render it in such a way. Generally, in latex this can be achieved with the \rm{} command. However, that does not work in matplotlib. Please help.

import numpy as np
import matplotlib.pyplot as plt

x = np.arange(10)
y = x

plt.plot(x,y,'ro')
plt.xlabel('Primary T$_{eff}$')

enter image description here

``\rm`` works for me. Just to be sure, are you escaping the backslash? — fjarri, Oct 30 '13 at 00:39
Are you using p3k? Escaping is going to get nasty. You might need to do `'\\rm{eff}'`. — tacaswell, Oct 30 '13 at 02:49
I would suggest using `$T_{\mathrm{eff}}$`, unless `T` is used in text mode within your document. — Werner, Oct 30 '13 at 03:02
\mathrm did the job for me. No, I am using Python 2.7. Thanks a lot all of you! — Rohit, Oct 30 '13 at 11:32

I have encountered this problem many times and it can be solved with this trick

plt.xlabel(r'Primary T$_{\rm eff}$')

In LaTeX2e the `\rm` command is deprecated, and should not be used. – sodd Aug 29 '14 at 18:16

'Primary T$_\mathrm{eff}$' also works if you are worried about deprecation. – nijoakim Nov 28 '16 at 10:34
