I am not familiar with tkinker; but, the expression is just showing a
function prototype.  The function part should be self-explanitory.  Judging
from statements below like:

canvasx(screenx) => float, canvasy(screeny) => float

and

bbox(items) => tuple, bbox() => tuple

and the fact that "id" is mentioned for all of the functions that return a
handle, I suspect that the "=>" and what comes after it is just a
typographical notation to tell the reader what kind of datatype they can
expect the function to return.
