### RcParams is a class in matplotlib package.
# It implements a dictionary object that holds all default values for plotting with matplotlib.
# rcParams is an object instance of RcParams in matplotlib package.
# It implements a dictionary object that stores default matplotlib parameters.
### rc_params() is a function in matplotlib package.
# It returns a matplotlib.RcParams() instance from the default matplotlib rc file.
import matplotlib as mpl
print mpl.rc_params()
# or print the dictionary object:
print mpl.rcParams
# you can either access it through matplotlib itself, or through matplotlib.PyPlot

# It sets the current rc parameters.
