If you want to create a new feature class from the selection arcpy.CopyFeatures_management will do it:

arcpy.CopyFeatures_management(SelectedFeatures,'afilepath\NewFeatures.shp')

The above presumes the output is a shapefile, if you were copying into a new geodatabase feature class you'd have to set up the reference to the gdb and drop the .shp from the name.

If you want the selection to go into an existing featureclass the the append tool is probably more what you are looking for.

I usually will use the MakeFeatureLayer command to make a layer from a feature class based on a query and then use CopyFeatures to export it out into its own feature class. I have an example below:

arcpy.MakeFeatureLayer_management(feature, feat_lyr)
    arcpy.SelectLayerByAttribute_management(feat_lyr, 'NEW_SELECTION', query)
    arcpy.SelectLayerByAttribute_management(feat_lyr, 'SUBSET_SELECTION', query3)
    
    result = arcpy.GetCount_management(feat_lyr)
    print "Number of selected addresses in the layer: " + str(result)

    #Copy selected features to new feature class
    if arcpy.Exists(output):
        arcpy.Delete_management(output)
        
    arcpy.CopyFeatures_management(feat_lyr, output)
    print "Copied selected features from urban points layer to: " + output

I hope this helps!
