Often an application (or e.g. a library's test suite), in its early development, will start making print() calls, and later will want to switch to the logging module. However the logging module doesn't offer any facility for this: you can't print() to a logger object, and loggers don't have a method that reflects print()'s signature.

(note print() only uses the .write() and .flush() methods on its stream argument, so a simple wrapper may make the trick)
