How do i find some text and symbols in string python 3.7 - python-3.x

Question

I need some help figuring out how to find TV (0) -> Broadcast (F): routing change (80)
From this lot....

this is code snipped from my project.

I made this but it doesn't work.

After Tom Robinson gave me a pointer in the right direction
here is the full code, the error i'm receiving is as he said but now I cannot fathom what arguments for event, level, time and message are needed
I've tried a few print commands to see if i can get the right info.
also tried if "routing change(80)" in log_cb(event, level, time, message): but get NameError: name 'event' is not defined
#!/usr/bin/env python

def log_cb(event, level, time, message):
print("CEC Log message:", message)
cec.add_callback(cb, cec.EVENT_ALL & ~cec.EVENT_LOG)
cec.add_callback(log_cb, cec.EVENT_LOG)

while True:
# if "routing change(80)" in "log_cb":

And the new error:

that while true is only there for testing as without it the script ends at line print(log_cb)

It should stop as soon as it sees the request change but it doesn't. arrrrggg
last update I tried a few different things after someone suggested print(message)so I tried this but I think the 0f:86:30:00 needs to be written in different format and have no idea how to to do that.
def log_cb(event, level, time, message):
print("CEC Log message:", message)
print(message)
if '0f:86:30:00' in message:
exit()
log message snipped with few lines ether side of the event :
CEC Log message: << POLL: TV (0) -> Recorder 2 (2)
CEC Log message: >> 0f:80:30:00:30:00

Answer 1

log_cb is a callback you provide to the cec module with cec.add_callback(log_cb, cec.EVENT_LOG). This is clearly a logging handler that cec calls automatically on certain events; it's not something that makes sense for you to call yourself. This handler seems working since you've shown the output from its print statement.
message contains the substring you're interested in, so move your substring check into log_cb and get rid of the while True: block which will (probably) freeze your program (I'm not familiar with the cec library, but it seems like the wrong way to keep the program alive to poll for events and I don't see it mentioned in the docs):
def log_cb(event, level, time, message):
print("CEC Log message:", message)
if "routing change (80)" in message:
print("routing change (80) was in the message")
Note that the line if "routing change (80)" in '$log_cb': is nonsensical because it's always false. '$log_cb' is a string literal, not a variable holding a value like you may think.
In your updated code:
if (message == "routing change(80)"):
There are two problems:
The real substring in the log you posted is "routing change (80)", not "routing change(80)" (the space matters).
message == "routing change (80)" is not the correct logic and will likely never be true based on the log you showed. "routing change (80)" in message is the correct logic because it checks whether the desired string is a substring of message rather than an exact match.

Answer 2

Your code is checking if "routing change(80)" is a substring of the string "$log_cb". If you are intending to run the function log_cb, you need to call it using log_cb():
while True:
if "routing change(80)" in log_cb():
print("it worked ")
You will need to pass arguments for event, level, time and message, otherwise you will get a TypeError
Hope this helps!
