Python, logging print statements while having them print to stdout

Question

I have a long python script that uses print statements often, I was wondering if it was possible to add some code that would log all of the print statements into a text file

If you use the built in logging module you can configure your loggers with as many outputs as you need: to file, to databases, to emails, etc. However it sounds like you're mixing print for two different uses: logging (recording program flow for later inspection) and prompts. The real work will be to split out those two uses of 'print' into different functions so you get what you need in each place.

A lot of people replace python's generic sys.stdout and sys.stderr to automatically do stuff to text which is being sent to the console. The real console output always lives in sys.__stdout__ and sys.__stderr__ (so you don't need to worry about somehow 'losing' it) but if you stick any object with the same methods as a file into the variables sys.stdout and sys.stderr you can do whatever you like with the output process.
