How to put formatted, highlighted code in a WordPress post

I found two complementary plugins that enable me to put highlighted formatted code in a WordPress page or post. Here’s an example of what they do:

# Plot flux at continuum boundary
pylab.figure()
pylab.hold(True)
pylab.plot(nd_times, Jl_BD, 'b-', label="Flux from BD simulation")
pylab.plot(nd_times, Jl_BD+Jl_BD_std, 'b.', label="Flux from BD simulation")
pylab.plot(nd_times, Jl_BD-Jl_BD_std, 'b.', label="Flux from BD simulation")

Test successful!  Note that Javascript must be enabled to see the highlighting. Get the plugins here:
