I got an error when I ran cv2.fillPoly(color_warp, pts, (0,255, 0)) and then recognized pts needed to be int32.
But why does it need to be int32 ?
pts holds an array of array of points on an image. An image is a matrix of Scalars. It is indiced by (X, Y) values which can be stored quite adequately in int32.

I have a string with brackets in it from which have to remove/strip the substring.
For ex:
"8383838383(1234)" //string value
"8383838383" // desired result.
Thanks in advance
"8383838383(1234)".substringToIndex(string.rangeOfString("(")!.startIndex)
// "8383838383"
Building on #Tim's suggestion -
let strFull = "8383838383(1234)"
var str = strFull.substringToIndex(strFull.rangeOfString("(")!.startIndex)

How to write something
if !inBoundary then do
printfn "no it's not within the boundary"
You can use the not built-in function (and omit the do keyword after then):
let inBoundary = false
if not inBoundary then
printfn "no it's not within the boundary"
