python draw circle matplotlib

list_t = list(np.arange(0,max_theta,0.0001))
x_circle = [(R*math.cos(x_y)) for x_y  in list_t]
y_circle = [(R*math.sin(x_y)) for x_y  in list_t]
#Plot
fig = plt.figure()
fig.set_size_inches(8, 8)
ax = fig.add_axes([0.15,0.2,0.7,0.7]) 
ax.plot(x_circle, y_circle, linestyle = 'solid', color = 'black')
