How to change legend fontname in matplotlib

I would like to display a font in Times New Roman in the legend of a matplotlib plot. I have changed all other tick labels/axis labels/titles to Times New Roman, and have searched the documentation but I can only find how to change the font size in a legend using the prop argument in pyplot.legend()

Of course straight after posting, I found the answer. Solution for anyone else with the same issue:

import matplotlib as mpl  
mpl.rc('font',family='Times New Roman')

Here is an example from 2023

plt.legend(
    labels,
    bbox_to_anchor=[1, 0, 0.5, 1],
    prop={'family':'monospace'}
)

prop={'family':'monospace'} - change legend font
bbox_to_anchor=[1, 0, 0.5, 1] - move legend to right upper conner

This wasn't showing up in google results so I'm going to post it as an answer. The rc parameters for font can be used to set a single default font.

Solution for anyone else with the same issue:

import matplotlib as mpl
mpl.rc('font',family='Times New Roman')

I think this is the better way. 

import matplotlib.font_manager as fm

## your font directory 
font_path = '/Users/frhyme/Library/Fonts/BMDOHYEON_otf.otf'

## font_name 
font_name = fm.FontProperties(fname=font_path).get_name()

plt.legend(prop={'family':font_name, 'size':20})

The .rc solution given changes the default font for all drawing.

Here is a solution for doing this when you don't want to change all the fonts, but just the font properties of the legend of this particular graph (a legend belonging to a particular axis object):

L = ax.legend()
plt.setp(L.texts, family='Consolas')

This allows you to choose a different font for the legend and the axes. I found this helpful when I needed a monospace font for my legend, but not for the axes -- allowing me to create a neat legend like this:

enter image description here

Note how the title is a different font than the legend - this gives me an alignment of numbers that would otherwise be hard to achieve.
