You can easily make a wrapper around print(), though. For example,
suppose you want a timestamped log file as well as the console:
from builtins import print as pront # mess with people
@functools.wraps(pront)
def print(*a, **kw):
if "file" not in kw:
logging.info(kw.get("sep", " ").join(a))
return pront(*a, **kw)
Now what happens if you add the errors handler? Does this function
need to handle that somehow?
