The pprint module provides a capability to “pretty-print” arbitrary Python data structures in a form which can be used as input to the interpreter. If the formatted structures include objects which are not fundamental Python types, the representation may not be loadable.
Use logging Module to Print Log Message to a File in Python getLogger(name) method. There is a convention to use __name__ variable as the name of the logger. Once we have created a new logger, we should remember to log all our messages using the new logger.info() instead of the root's logging.info() method.
Use pprint.pformat to get a string, and then send it to your logging framework.
from pprint import pformat
ds = [{'hello': 'there'}]
logging.debug(pformat(ds))
The solution above didn't quite cut it for me because I'm also using a formatter to add name and levelname when logging. It looks a little untidy:
__main__ : DEBUG : ['aaaaaaaaaaaaaaaaaaaa',
'bbbbbbbbbbbbbbbbbbbb',
'cccccccccccccccccccc',
'dddddddddddddddddddd']
__main__ : DEBUG : Some other logging text
There may be a more elegant solution, but this:
for line in pprint.pformat(ds).split('\n'):
logging.debug(line)
produces something a little nicer:
__main__ : DEBUG : ['aaaaaaaaaaaaaaaaaaaa',
__main__ : DEBUG : 'bbbbbbbbbbbbbbbbbbbb',
__main__ : DEBUG : 'cccccccccccccccccccc',
__main__ : DEBUG : 'dddddddddddddddddddd']
__main__ : DEBUG : Some other logging text
