Vinay Sajip added the comment: In recent versions of Python, information *is* printed which allows pinpointing the source of the formatting error. Consider the following script, logex.py:
import logging logger = logging.getLogger(__name__) def test(): logger.debug('The result is ', 'abc') def main(): test() if __name__ == '__main__': logging.basicConfig(level=logging.DEBUG) main() When this is run with Python 2.7: $ python logex.py Traceback (most recent call last): File "/usr/lib/python2.7/logging/__init__.py", line 842, in emit msg = self.format(record) File "/usr/lib/python2.7/logging/__init__.py", line 719, in format return fmt.format(record) File "/usr/lib/python2.7/logging/__init__.py", line 464, in format record.message = record.getMessage() File "/usr/lib/python2.7/logging/__init__.py", line 328, in getMessage msg = msg % self.args TypeError: not all arguments converted during string formatting Logged from file logex.py, line 6 With Python 3.2: $ python3.2 logex.py Traceback (most recent call last): File "/usr/lib/python3.2/logging/__init__.py", line 937, in emit msg = self.format(record) File "/usr/lib/python3.2/logging/__init__.py", line 812, in format return fmt.format(record) File "/usr/lib/python3.2/logging/__init__.py", line 551, in format record.message = record.getMessage() File "/usr/lib/python3.2/logging/__init__.py", line 319, in getMessage msg = msg % self.args TypeError: not all arguments converted during string formatting Logged from file logex.py, line 6 As you can see, the filename and line number are identified, so you can see precisely where the formatting error is. ---------- components: +Library (Lib) -Extension Modules resolution: -> invalid status: open -> pending _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18671> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
