Invece di reinventare la ruota potresti usare il modulo logging.
Da "pydoc logging":
class Formatter
| Formatter instances are used to convert a LogRecord to text.
|
| Formatters need to know how a LogRecord is constructed. They are
| responsible for converting a LogRecord to (usually) a string which can
| be interpreted by either a human or an external system. The base Formatter
| allows a formatting string to be specified. If none is supplied, the
| default value of "%s(message)\n" is used.
|
| The Formatter can be initialized with a format string which makes use of
| knowledge of the LogRecord attributes - e.g. the default value mentioned
| above makes use of the fact that the user's message and arguments are pre-
| formatted into a LogRecord's message attribute. Currently, the useful
| attributes in a LogRecord are described by:
|
| %(name)s Name of the logger (logging channel)
| %(levelno)s Numeric logging level for the message (DEBUG, INFO,
| WARNING, ERROR, CRITICAL)
| %(levelname)s Text logging level for the message ("DEBUG", "INFO",
| "WARNING", "ERROR", "CRITICAL")
| %(pathname)s Full pathname of the source file where the logging
| call was issued (if available)
| %(filename)s Filename portion of pathname
| %(module)s Module (name portion of filename)
| %(lineno)d Source line number where the logging call was issued
| (if available)
| %(created)f Time when the LogRecord was created (time.time()
| return value)
| %(asctime)s Textual time when the LogRecord was created
| %(msecs)d Millisecond portion of the creation time
| %(relativeCreated)d Time in milliseconds when the LogRecord was created,
| relative to the time the logging module was loaded
| (typically at application startup time)
| %(thread)d Thread ID (if available)
| %(process)d Process ID (if available)
| %(message)s The result of record.getMessage(), computed just as
| the record is emitted
