Bases:
Formatter
Custom log formatter which attaches all the attributes from the “extra” dictionary which start with an underscore to the end of the log message.
For example: extra={‘_id’: ‘user-1’, ‘_path’: ‘/foo/bar’}
Initialize the formatter with specified format strings.
Initialize the formatter either with the specified format string, or a default as described above. Allow for specialized date formatting with the optional datefmt argument. If datefmt is omitted, you get an ISO8601-like (or RFC 3339-like) format.
Use a style parameter of ‘%’, ‘{’ or ‘$’ to specify that you want to use one of %-formatting,

parameter.- format(record)[source]¶
Format the specified record as text.
The record’s attribute dictionary is used as the operand to a string formatting operation which yields the returned string. Before formatting the dictionary, a couple of preparatory steps are carried out. The message attribute of the record is computed using LogRecord.getMessage(). If the formatting string uses the time (as determined by a call to usesTime(), formatTime() is called to format the event time. If there is exception information, it is formatted using formatException() and appended to the message.
