Indeed. I have a cs.logutils module, which is almost entirely support for the
logging module (standard setups, funky use cases), but it also defines two
functions, X and D, thus:
def X(fmt, *args):
msg = str(fmt)
msg = msg % args
def D(fmt, *args):
''' Print formatted debug string straight to sys.stderr if D_mode is true,
bypassing the logging modules entirely.
A quick'n'dirty debug tool.
I use X() for ad hoc right now debugging and D() for turn on at need debugging.
Surprisingly handy. Many many of my modules have "from cs.logutils import X, D"
at the top.
