Python: Logging TypeError: not all arguments converted during string formatting

Question

Here is what I am doing

>>> import logging
>>> logging.getLogger().setLevel(logging.INFO)
>>> from datetime import date
>>&g         


        

Answer 1

You could do the formatting yourself:

logging.info('date={}'.format(date))

As was pointed out by Martijn Pieters, this will always run the string formatting, while using the logging module would cause the formatting to only be performed if the message is actually logged.
