looking for a custom exception

[JarredAwesome]

Hey everyone,

I am working on a python script that uses a thermometer. I want to put a line of code in that test to make sure the thermometer is hooked up, so I using "try except".

I found a library that seems to do a good job, but the error code that comes back when the thermometer is missing is:

w1thermsensor.errors.NoSensorFoundError: 
Could not find sensor of type DS18B20 with id 0300a27989942
Please check cabling and check your /boot/config.txt for
dtoverlay=w1-gpio

is there a way I can tell Try ... Except to look for that error in particular?

I tried:

try:
   verify code:
except w1thermsensor.errors.NoSensorFoundError
   return results

Any ideas?

Thanks
