I have written a python script tool wherein a user specifies a feature class (e.g., Landuse) containing different attributes (e.g., parcel size, landcover etc.), name of the attribute field from which features will be selected (e.g., "landcover") and the name of the attribute to be selected (e.g., "forest" or "buildings"). The end result should be that the script selects all the features with the specified attribute and create a new feature class out of it. For this I have 3 input parameters, as shown below, and the script receives the input with GetParameterAsText().
My code block looks like follows:
FClass = arcpy.GetParameterAsText(0) Field = arcpy.GetParameterAsText(1) Feature = arcpy.GetParameterAsText(2)arcpy.MakeFeatureLayer_management(FClass, "FclassLayer")arcpy.SelectLayerByAttribute_management("FclassLayer","NEW_SELECTION","'Field' = 'Feature'")arcpy.CopyFeatures_management("FclassLayer", "Feature1.shp")When I run the script tool, it doesn't produce any error message and creates Feature1.shp, but the shapefile is simply a copy of the specified feature class. That means, SelectLayerByAttribute is simply selecting the whole feature class irrespective of the specified attribute.
Being a beginner with python scripting, I am not being able to locate what am I doing wrong here. Furthermore, I tested the same script with hard coded values instead of getting it from user with GetParameterAsText, and there it runs perfectly and gets me the output as expected.
