With ptvsd:

import ptvsd
ptvsd.enable_attach(('localhost', 5678))
ptvsd.wait_for_attach()


ptvsd.break_into_debugger()
print('break here')

With debugpy:

import debugpy
debugpy.listen(('localhost', 5678))
debugpy.wait_for_client()


debugpy.breakpoint()
print('break here')

with ptvsd:

> python ptvsd --host localhost --port 5678 --wait ./myscript.py

With debupy:

> python debugpy --listen localhost:5678 --wait-for-client ./myscript.py
