A quick peak into threading.py reveals
# Helper to generate new thread names
_counter = 0
def _newname(template="Thread-%d"):
global _counter
_counter += 1
return template % _counter
class Thread:
...
def __init__(self, group=None, target=None, name=None,
args=(), kwargs=None, *, daemon=None):
...
self._name = str(name or _newname())
There is no upper limit to the thread name other than that you will
eventually run out of memory ;)
