Snapping points to line yields error 000800?

Question

I am trying to snap points (temp2.shp) to nearest line (Rail2.shp) at any of its vertex within any distance.

ArcPy code:

temp2 = "M:\\temp2.shp"
arcpy.Snap_edit(temp2, ["M:\\Rail2", "VERTEX", '10000 Feet'])

Error Message:

Failed to execute. Parameters are not valid.
ERROR 000800: The value is not a member of END | VERTEX | EDGE.
ERROR 000800: The value is not a member of END | VERTEX | EDGE.
ERROR 000800: The value is not a member of END | VERTEX | EDGE.

Answer 1

This answer to ERROR 000800 when trying to snap points layer to line or buffer layer helped.

Adding a set of square brackets on top of the existing square brackets.

Working code:

temp2 = "M:\\temp2.shp"
arcpy.Snap_edit(temp2, [["M:\\Rail2", "VERTEX", '10000 Feet']])
