Placeholder Variables in Schript

Question

hi,

i wrote the following script. it is supposed to select feature classes out of a featuredataset, based on the feature class stored in another geodatabase. it works fine so far. but i want to make it more flexible.
in the following line for example:if FeatureToPoint == "in_memory\A_FeatureToPoint": arcpy.Select_analysis(locationstands, outfeatureclass, ""identify" = 'A'"); arcpy.AddMessage("worksA")

"in_memory\A_FeatureToPoint" shall be somehow get connected to ""identify" = 'A'". so the two "A"s shall get connected.

i have a hard time expressing what i want. i hope you guys understands me and can help me.

thanks,

uli

here is the full code:# Import:
import arcpy
import sys
import os
from arcpy import env

# Variables:

FeatureToPoint = arcpy.GetParameterAsText(0)
locationstands = arcpy.GetParameterAsText(1)
outfeatureclass = arcpy.GetParameterAsText(2)

if FeatureToPoint == "in_memory\A_FeatureToPoint": arcpy.Select_analysis(locationstands, outfeatureclass, ""identify" = 'A'"); arcpy.AddMessage("worksA")
elif FeatureToPoint == "in_memory\B_FeatureToPoint": arcpy.Select_analysis(locationstands, outfeatureclass, ""identify" = 'B'"); arcpy.AddMessage("worksB")
elif FeatureToPoint == "in_memory\C_FeatureToPoint": arcpy.Select_analysis(locationstands, outfeatureclass, ""identify" = 'C'"); arcpy.AddMessage("worksC")
elif FeatureToPoint == "in_memory\D_FeatureToPoint": arcpy.Select_analysis(locationstands, outfeatureclass, ""identify" = 'D'"); arcpy.AddMessage("worksD")
elif FeatureToPoint == "in_memory\E_FeatureToPoint": arcpy.Select_analysis(locationstands, outfeatureclass, ""identify" = 'E'"); arcpy.AddMessage("worksE")
elif FeatureToPoint == "in_memory\F_FeatureToPoint": arcpy.Select_analysis(locationstands, outfeatureclass, ""identify" = 'F'"); arcpy.AddMessage("worksF")
elif FeatureToPoint == "in_memory\G_FeatureToPoint": arcpy.Select_analysis(locationstands, outfeatureclass, ""identify" = 'G'"); arcpy.AddMessage("worksG")
elif FeatureToPoint == "in_memory\H_FeatureToPoint": arcpy.Select_analysis(locationstands, outfeatureclass, ""identify" = 'H'"); arcpy.AddMessage("worksH")
elif FeatureToPoint == "in_memory\I_FeatureToPoint": arcpy.Select_analysis(locationstands, outfeatureclass, ""identify" = 'I'"); arcpy.AddMessage("worksI")
elif FeatureToPoint == "in_memory\J_FeatureToPoint": arcpy.Select_analysis(locationstands, outfeatureclass, ""identify" = 'J'"); arcpy.AddMessage("worksJ")
elif FeatureToPoint == "in_memory\AA_FeatureToPoint": arcpy.Select_analysis(locationstands, outfeatureclass, ""identify" = 'AA'"); arcpy.AddMessage("worksAA")

else: arcpy.AddMessage("doesntwork")

arcpy.Select_analysis(locationstands, outfeatureclass, "identify = '%s'" % feature_label)

it seems to work. thank you guys!

okay, i am quite knew to this. just started using python last week.

i changed the code to the following
FeatureToPoint = arcpy.GetParameterAsText(0)
feature_label = arcpy.GetParameterAsText(1)
locationstands = arcpy.GetParameterAsText(2)
outfeatureclass = arcpy.GetParameterAsText(3)

if FeatureToPoint == "U:\Intern\Ulrich\fairbanks_biomass\test.gdb\%s_FeatureToPoint" % feature_label: 
    arcpy.Select_analysis(locationstands, outfeatureclass, "identify = '%s'" % feature_label)
    arcpy.AddMessage("works%s" % feature_label)

else: arcpy.AddError("doesntwork")

and i made the "feature_label" parameter to string. but what shall i now put in there?

here is the part of my model, it might help to understand the process

Also, I bet you can drop the "\" stuff in the SQL. I think this confusing \ notation is a holdover formatting thing for shapefiles/dbf tables from v9.0 - 9.2, but not necessary in v9.3+

#so instead of this:
arcpy.Select_analysis(locationstands, outfeatureclass, "\"identify\" = '%s'" % feature_label

#try this:
arcpy.Select_analysis(locationstands, outfeatureclass, "identify = '%s'" % feature_label)
