@pmcao This is just using the default logging format. You can have it display whatever you want. See the Formatter docs:
http://docs.python.org/2/library/logging.html#logging.Formatter
Thanks for throwing this together.
I really like your approach. Do you know how to avoid the ANSI escape codes in the log files if I add a file handler?
@elsa-heer I know it has been a long time since you commented on this, but I also needed to avoid the the ANSI escape sequences in the log file. Here is the solution I came up with: https://gist.github.com/KurtJacobson/c87425ad8db411c73c6359933e5db9f9

This is excellent! However it does not print current function name in logging! Perhaps because of the lambda keyword in line 21?
