Dear Group,

I am trying to enumerate few interesting errors on pylab/matplotlib. 
If any of the learned members can kindly let me know how should I address them.

I am trying to enumerate them as follows.

i) >>> import numpy
>>> import pylab
>>> t = numpy.arange(0.0, 1.0+0.01, 0.01)
>>> s = numpy.cos(2*2*numpy.pi*t)
>>> pylab.plot(t, s)
[<matplotlib.lines.Line2D object at 0x021122D0>]
>>> pylab.show()
Exception in Tkinter callback
