Thank you for your reply, Tamas. But when I use plot(dd), I got a type error:
BTW, i'm using python 3.5.1

__plot__ is an internal function; you are not supposed to call it
directly. Call the plot() function instead:
>>> dd = g.degree_distribution()
>>> plot(dd)
or, if the plot is not shown automatically, then:
>>> plot(dd).show()
