Sure. This is like yours but slightly nicer and deals with graphics
nicely (and also lists of graphics objects):
def pretty_print (object):
if object is None:
return
if isinstance(object, (sage.plot.plot.Graphics,
sage.plot.plot3d.base.Graphics3d)):
print repr(object)
return
import __builtin__
__builtin__._=object
try:
print html("$$"+latex(object)+"$$")
except:
import sys
sys.__displayhook__(object)
def notebook_pretty(enable=True):
import sys
if enable:
sys.displayhook = pretty_print
else:
sys.displayhook = sys.__displayhook__
# To enable the pretty-printing
notebook_pretty(True)
