python animation ... passing an argument -


i have simple python animation program downloaded. changing around understand animation calls little better. program makes simple dot move in circle on screen. placed functions change dot's position , animation calls each class. worked ok. put definition of figure class. works ok too. how looks,

import numpy np import matplotlib.pyplot plt import matplotlib.animation animation  class fig:     def __init__(self):         self.fig=plt.figure()         self.ax = self.fig.add_subplot(111)         self.line, = self.ax.plot([], [], 'bo', ms=10)         self.ax.set_ylim(-1, 1)         self.ax.set_xlim(-1, 1) class sd:         def simdata(self):         t_max = 100.0         dt = 0.001         x = 0.0         t = 0.0         while t < t_max:             x = np.sin(np.pi*t)             t = t + dt             y = np.cos(np.pi*t)             yield x, y class sp:     def simpoints(self,simdata):         x, t = simdata[0], simdata[1]         f1.line.set_data(t, x)         return f1.line #line2#, time_text  f1=fig() sd=sd() sp=sp()  ani = animation.funcanimation(f1.fig, sp.simpoints, sd.simdata, blit=false,      interval=10, repeat=true)  plt.show()

now, want pass figure instace argument through animation call. not work, new code not work....

import numpy np import matplotlib.pyplot plt import matplotlib.animation animation  class fig:     def __init__(self):         self.fig=plt.figure()         self.ax = self.fig.add_subplot(111)         self.line, = self.ax.plot([], [], 'bo', ms=10)         self.ax.set_ylim(-1, 1)         self.ax.set_xlim(-1, 1) class sd:         def simdata(self):         t_max = 100.0         dt = 0.001         x = 0.0         t = 0.0         while t < t_max:             x = np.sin(np.pi*t)             t = t + dt             y = np.cos(np.pi*t)             yield x, y class sp:     def simpoints(self,simdata,figg):         x, t = simdata[0], simdata[1]         figg.line.set_data(t, x)         return figg.line #line2#, time_text  f1=fig() sd=sd() sp=sp()  ani = animation.funcanimation(f1.fig, sp.simpoints, sd.simdata, f1, blit=false,      interval=10, repeat=true)  plt.show()

the compiler tells me,

self._drawn_artists = self._init_func() attributeerror: fig instance has no __call__ method

any comments appreciated. thanks

c# - Validate object ID from GET to POST -

i have method allows user access comment have made on site. have post method lets them update comment. my normal solution send entire comment model through, let them update it, update on database when post back. involve sending commentid through in hiddenfor , can manipulated. how can verify commentid sent in get method same i'm getting in post , not able alter comment wish? how can verify commentid sent in method same i'm getting in post? basically have validate following things in post - user logged-in user. authenticated users post comments. commentid in post , should valid commentid , should present in database. userid associated logged-in user should same userid associated comment . comment should contain userid column, can check @ time of update. to make sure update happens comment has been sent in get - hold commentid in session , in post action compare commentid value in session .
