If you're using Python 3, you can shadow print() with your own function. The logging functions don't have the same signature, so you'd need to write a wrapper (or else stick to a strict policy of "one argument to print() and it must be a string"), but it's certainly possible. But part of the point of the logging module is that it's not the same as console messages: you can reduce log spam by changing the logging level. So no, you don't have a guarantee that all console messages will be logged to the log file. If you want that, I would suggest a process-level wrapper - something which invokes a subprocess with redirected stdout and/or stderr - or, at very least, a startup routine that does the redirection (which will have similar effect, except that it can't catch startup failure messages from Python itself).
