looking for a custom exception

[JarredAwesome]

Also, show as your imports with respect to w1thermsensor or w1thermsensor.errors

Looking at the project __init__.py they import their custom errors at to level, so

import w1thermsensor
try:
    my_sensor = w1thermsensor.W1ThermSensor()
except w1thermsensor.NoSensorFoundError
    print('No sensor found')

Here is my version of that:

from w1thermsensor import W1ThermSensor

try:                
	sensor = W1ThermSensor(W1ThermSensor.THERM_SENSOR_DS18B20, '0300a27989945')
except w1thermsensor.errors.NoSensorFoundError:
	print('Thermometer not Found')

here is the output:

Error:
Traceback (most recent call last):
  File "curl.py", line 5, in <module>
    sensor = w1ThermSensor(w1ThermSensor.THERM_SENSOR_DS18B20, '0300a27989945')
NameError: name 'w1ThermSensor' is not defined

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "curl.py", line 6, in <module>
    except w1thermsensor.errors.NoSensorFoundError:
NameError: name 'w1thermsensor' is not defined

Here is what is in the modules __init__.py file

from .__version__ import __version__  # noqa
from .core import W1ThermSensor  # noqa
from .errors import NoSensorFoundError  # noqa
from .errors import SensorNotReadyError  # noqa
from .errors import UnsupportedUnitError  # noqa
from .errors import ResetValueError  # noqa

here is a file called errors.py in the module dir

I can't really find where the errors are called
