Can I redirect all output from stdout to a logger I have set up with the standard logging module?
(I have os.system calls whose output I'd also like to see or occational print statements)

Thanks! Somehow the automatic suggestions only showed stdout redirection to files...Gere– Gere2012-02-23 10:20:04 +00:00Commented Feb 23, 2012 at 10:20

You might be able to make use of the suggestion in this post, summarised below:
import logging
class LoggerWriter:
def __init__(self, logger, level):
self.logger = logger
self.level = level
def write(self, message):
if message != '\n':
self.logger.log(self.level, message)
def main():
logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger("demo")
info_fp = LoggerWriter(logger, logging.INFO)
debug_fp = LoggerWriter(logger, logging.DEBUG)
print >> info_fp, "An INFO message"
print >> debug_fp, "A DEBUG message"
if __name__ == "__main__":
main()
When run, the script prints:
INFO:demo:An INFO message
DEBUG:demo:An DEBUG message
