Python syntax help, output to new Feature Class

My code looks something like this (below).
What I need is pretty simple, I just can't figure out the proper syntax. 
Basically I want to define some dates (def dates)
Some plant types (def plants)
and some abbreviations for those plant types (def Abvs)
and then I want to call those functions (I hope that's the correct term, I'm not a programmer as you can tell) as part of my output names.  If I can figure this out, this will save me soooo much time. 
I would really appreciate any thoughts on what to do here.


# Create the Geoprocessor
import arcgisscripting
gp = arcgisscripting.create(9.3)

# Set a default workspace
gp.workspace = "C:\\working\\Physical\\pgdb"

#studyarea = SA04

def dates():
Date1 = SA04_Ph_0809
Date2 = SA04_Ph_1009

def plants():
plant1 = Absent
plant2 = Cabomba carolinia

def Abvs():
p1abv = Abs
p2abv = Cab

    # Make a layer from the feature class
    gp.MakeFeatureLayer("C:\\working\\Physical\\pgdb\\testing.gdb\\Date1", "lyr1")

    # Select plants of a species type
    gp.SelectLayerByAttribute("lyr1", "NEW_SELECTION", " genspec1 = 'plant1'")

    # Add to previous selection
    gp.SelectLayerByAttribute("lyr1", "ADD_TO_SELECTION", " genspec2 = 'plant1")   

    # Write the selected features to a new featureclass named for date and plant type
    gp.CopyFeatures("lyr1", "C:\\working\\Physical\\pgdb\\testing.gdb\\SA04_out\\Date1 + "_" + p1abv")

    # If an error occurred print the message to the screen
    print gp.GetMessages()
