Sorry I did not include the errors that I have been getting, but here they
are:
>>> from mapnik import *
>>> m= Map(800,600, "+proj=latlong +ellps= WGS84")
>>> m.background = Color('white')
>>> hydropoints_lyr= Layer('Hydrobrakes')
>>> hydropoints_lyr.datasource =
Shapefile(file='E:/Hydrobrakes/hydrobrakes', encoding='latin1')
>>> hydropoints_style = Style()
>>> hydropoints_rule_on = Rule()
>>> hydropoints_rule_on.filter = Filter("[STATUS] = 'ACT'")
>>> hydropoints_rule_on.symbols.append(PointSymbolizer(file
='E:/Hydrobrakes/hydrobrakes.png',type ='png',width= '2', height= '2'))
Traceback (most recent call last):
File "<pyshell#8>", line 1, in <module>
hydropoints_rule_on.symbols.append(PointSymbolizer(file
='E:/Hydrobrakes/hydrobrakes.png',type ='png',width= '2', height= '2'))
ArgumentError: Python argument types in
PointSymbolizer.__init__(PointSymbolizer)
did not match C++ signature:
__init__(struct _object *, class std::basic_string<char,struct
std::char_traits<char>,class std::allocator<char> >, class
std::basic_string<char,struct std::char_traits<char>,class
std::allocator<char> >, unsigned int, unsigned int)
__init__(struct _object *)

Thanks again for the reply and the help.
