You can just use "dir(gr)", or something like: for g in dir(gr): print g OR: print "\n".join([g for g in dir(gr)]) Both of these will print all available objects in gr, one per line. Also, you can use iPython as a command-line Python interpreter shell. In iPython, typing "dir(gr)" will print the objects as a column, too. Tom
