[Plplot-cvs] SF.net SVN: plplot:[9136] trunk/examples/python

[<and...@us...>]

Revision: 9136
          http://plplot.svn.sourceforge.net/plplot/?rev=9136&view=rev
Author:   andrewross

Log Message:
-----------
Update python examples 1, 3, 13 and 29 consistent with recent C 
example changes. Note example 31 is not yet implemented. Also note 
that example 1 does not work correctly with pythondemos.py since it 
now uses plstar rather than plinit and plssub.
