[issue43534] turtle.textinput window is not transient

New submission from Chris Winkler : When `turtle.textinput` is called in Python 3.9.2, the resulting dialog window is not marked as transient. This is not a problem in 3.9.1. The offending change seems to come from bpo-42630. Specifically, `SimpleDialog.__init__` is being passed `parent=None`

[issue43535] Make str.join auto-convert inputs to strings.

New submission from Raymond Hettinger : Rather than just erroring-out, it would be nice if str.join converted inputs to strings when needed. Currently: data = [10, 20, 30, 40, 50] s = ', '.join(map(str, data)) Proposed: s = ', '.join(data) That would simplify a common idiom. T
