asyncio.Task.print_stack
is described by documentation as having a default output file ofsys.stderr
. However, the defaultNone
is passed all the way toprint
statements, leading to an actual default ofsys.stdout
.Fix by setting the file to
sys.stderr
when the default is used.asyncio.Task.print_stack
doesn't usesys.stderr
