Logging prevents Flask application from starting

I am using the hello world version of Flask. I would like to add logging to a file. When I add the following line, the Flask app never starts:



logging.basicConfig(filename=os.path.join(os.path.dirname(os.path.realpath(__file__)), 'errors.txt'),

                        level=logging.ERROR)


Full code:



import logging

import os



from flask import Flask



app = Flask(__name__)





@app.route('/')

def hello_world():

    return 'Hello, World!'





logging.basicConfig(filename=os.path.join(os.path.dirname(os.path.realpath(__file__)), 'errors.txt'),

                    level=logging.ERROR)



app.run()





python-2.7 logging flask

          What visual should I use to simply compare current year value vs last year in Power BI desktop

          Image
          0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?

Is there a nice way to tell the pytest that "It's not a bug it's a feature" and tests should pass even when they get this warning? Is there other way than using something like: with pytest.warns(UserWarning): ...
