**What you expected to happen**:
I have been experimenting (for the first time) with trying to get the
PythonOperator to work -- and to see where I can get the log output to go.
I have 2 functions listed below.
The first function, print_context, causes my laptop to run out-of-memory --
and I have to reboot it. Shown farther below is how I tried to call it, but
that was commented out in order to try the 2nd function after the reboot.
The second function, my_function, caused the Airflow UI to pop-up the
"Something bad has happened." message.
I have not been able to get the PythonOperator to work.
**How to reproduce it**:
```
def print_context(ds, **kwargs):
import logging
import pprint
pprint(kwargs)
print(ds)
tlogger = logging.getLogger("airflow.task")
tlogger.info(f"kwargs: {kwargs}")
return 'done!'
def my_function(arg1):
import logging
print(f"arg1: {arg1}")
tlogger = logging.getLogger("airflow.task")
tlogger.info(f"arg1: {arg1}")
return 'done!'
```
With this in the dag:
```
LoggingMixin().log.info("hello from mixin logger")
# run_printlog = PythonOperator(
# task_id='print_it',
# provide_context=True,
# python_callable=print_context,
# dag=dag)
run_printlog = PythonOperator(
task_id='log_it',
python_callable=my_function,
op_kwargs={
'duglog': theloglevel
},
dag=dag)
log.info(f"after python operator")
```

As minimally and precisely as possible. Keep in mind we do not have access
to your cluster or dags.
If you are using kubernetes, please attempt to recreate the issue using
minikube or kind.

If this is a UI bug, please provide a screenshot of the bug or a link to a
youtube video of the bug in action
You can include images using the .md style of
To record a screencast, mac users can use QuickTime and then create an
unlisted youtube video with the resulting .mov file.
