Matplotlib, Как нарисовать заштрихованный круг в три четверти или дугу? ⇐ Python

[Anonymous]

Is that possible to use matplotlib.patches to plot a hatched three quarter circle? Like below.

Actually, I tried and I got this.

But it differs from what I really want. Someone can help me？
I want to draw some special shapes by using Python.
