Yes, and it is called "characteristic":
sage: RR.characteristic()
0
sage: GF(64,'a').characteristic()
2
It also works for rings:
sage: ZZ.characteristic()
0
sage: GF(64,'a')['t'].characteristic()
2
Generally, if you have a guess how a method of an object (say, ZZ) is
called, you may use tab-completion:
sage: R = GF(64,'a')['t']
sage: R.cha<press tab-key>
R.change_ring R.change_var R.characteristic
And you can also do some search:
sage: search_def('characteristic')
sage: search_src('characteristic')
sage: search_doc('characteristic')
which in this case would probably not be helpful since it gives too
many answers.
Cheers,
Simon
