Looks like I need to read *all* of the docstrings. I wish there was 
an easy way to search them....

gca().yaxis.grid(True)
gca().xaxis.grid(False)
Here is the grid method docstring:
 def grid(self, b=None, which='major', **kwargs):
 """
 Set the axis grid on or off; b is a boolean use which =
 'major' | 'minor' to set the grid for major or minor ticks
 if b is None and len(kwargs)==0, toggle the grid state. If
 kwargs are supplied, it is assumed you want the grid on and b
 will be set to True
 kwargs are used to set the line properties of the grids, eg,
 xax.grid(color='r', linestyle='-', linewidth=2)

HI. I wand to have just horizontal grid lines. Is there any way to do 
this? Thanks!

I don't recognize the error output at all, but it looks like you have an 
old version. The current release is 0.87.7. I don't know of any 
released version in which contour_demo.py did not run at all, though.
The X errors make me wonder whether you are trying to run from inside an 
IDE.
My suggestion would be to delete the installation you have, do a fresh 
install of the current version, and then try running demos on the 
command line, making sure the demos are from the newly installed version.
If you still have a problem, tell us what version you are running, how 
it was installed, and on what kind of system.
