When plotting a plot using matplotlib:

How to remove the box of the legend?

plt.legend(frameon=False)

How to change the color of the border of the legend box?

leg = plt.legend()
leg.get_frame().set_edgecolor('b')

How to remove only the border of the box of the legend?

leg = plt.legend()
leg.get_frame().set_linewidth(0.0)

For the matplotlib object oriented approach:

axes.legend(frameon=False)

leg = axes.legend()
leg.get_frame().set_edgecolor('b')
leg.get_frame().set_linewidth(0.0)

One more related question, since it took me forever to find the answer:

How to make the legend background blank (i.e. transparent, not white):

legend = plt.legend()
legend.get_frame().set_facecolor('none')

Warning, you want 'none' (the string). None means the default color instead.
