What is the correct way to use measureOnLine attribute for polyline?

CharithKarandana

I created a polyline myself and testing the measureOnLine attribute to use it in another script which goes with real data. "polyline.measureOnLine((x, y))" doesn't work ("I'm pretty much sure the point (x,y) is on the polyline. The funny thing is

"polyline.measureOnLine(polyline.positionAlongLine(length))" works (Although there is no use of such). So I believe there is something is missing form me. Can anyone help me to overcome this?

Polyline—ArcPy classes | ArcGIS Desktop 

measureOnLine (in_point, {use_percentage})

in_point has to be a point object and use_percentage is a boolean.

Your 'ValueError' is because you didn't provide the required object

So you need to make a point or use a point from some other object

ie arcpy.Point(x, y)

where x, y are coordinates.
