Installation
notwork needs Python 3.14 or later, and has no dependencies.
pip install notwork
Or with uv:
uv add notwork
Usage
Check a port number
is_port_in_range says whether a port number is valid, and check_port_is_in_range raises PortOutOfRangeError when it isn't.
from notwork import check_port_is_in_range, is_port_in_range
is_port_in_range(8000)
# True
check_port_is_in_range(70000)
# PortOutOfRangeError: Port 70000 must be 1-65535
Check for IPv6
has_ipv6 says whether this machine can bind ::1, the IPv6 loopback address.
from notwork import has_ipv6
has_ipv6()
# True when this machine can bind ::1
Claim a port
claim_port claims a port on every address that localhost can mean, and returns a ClaimedPort to listen on.
If another program is already using the port on localhost, it raises PortInUseError.
On Linux, the sockets are already listening when they're returned. On Windows, another program can still bind the port on :: with a socket that accepts IPv4 and IPv6 at once.
from notwork import claim_port
with claim_port(8000) as port:
# Bound to 127.0.0.1, and ::1 when there's IPv6
for sock in port.sockets:
sock.listen()
# Leaving the `with` block closed the port.
