UnboundLocalError: local variable 'hop' referenced before assignment

[rifen]

Using your library I am having issues with the traceroute portion. Below is my code. I feel like I have practically followed your example besides using input instead of a pre-defined IP.

from icmplib import ping, multiping, traceroute, Host, Hop
def trace(addresses):
for address in addresses:
hops = traceroute(
"{address}", count=3, interval=0.5, timeout=2, max_hops=10, fast_mode=False,
)
print(address)
print("Distance (ttl) Address Average round-trip time")
last_distance = 0
for hop in hops:
if last_distance + 1 != hop.distance:
print("****")
print(f"{hop.distance} {hop.address} {hop.avg_rtt} ms")
last_distance = hop.distance

I am a beginner so maybe I am doing something wrong but it seems like hop isn't defined in your library.

Hi, thank you for using my library 😃

The error you get may be related to an indentation error. Can you repost your indented code into a code block (or take a screenshot of your code)?

Otherwise, this line is incorrect:
hops = traceroute("{address}", count=3, interval=0.5, timeout=2, max_hops=10, fast_mode=False)

"{address}" is a string. It is not the address variable. Use instead:
hops = traceroute(address, count=3, interval=0.5, timeout=2, max_hops=10, fast_mode=False)

I hope this will help you.
