b'_silk' vs '_silk'

I was trying to get the number of silk ties. The data sample that I pass to the function is a numpy object and not a csv.reader list. When I pass '_silk' to be matched I get zero ties. When I pass b'_silk' it gives 3381 ties while the correct number is 3382. What is going on?

'_silk' is a unicode string in Python 3, b'_silk' is a bytes object (see docs on data types). numpy needs bytes not strings.

Is the "3381" the 0-based count": 3382 items numbered 0 through 3381?
