And omit the , after except. –Sven Marnach Jan 14 '11 at 11:35 2 @SvenMarnach, if you omit the , after except, you'll get global name 'e' is not defined, which is not much better than wrong syntax. –Val Nov 18 '13 at 11:11 4 @Val: Should be except Exception as e or except Exception, e, depending on Python version. –Sven Marnach Nov 19 '13 at
you have probably seen some. There are (at least) two distinguishable kinds of errors: syntax errors and exceptions. 8.1. Syntax Errors¶ python exception message attribute Syntax errors, also known as parsing errors, are perhaps the most

This module provides a standard interface to extract, format and print stack traces of Python programs. It exactly mimics the behavior of the Python interpreter https://docs.python.org/2/library/traceback.html when it prints a stack trace. This is useful when you want to print stack traces under program control, such as in a "wrapper" around the interpreter. The module uses traceback objects -- this is the object type that is stored in the variables sys.exc_traceback (deprecated) and sys.last_traceback and returned as the third item python exception from sys.exc_info(). The module defines the following functions: traceback.print_tb(tb[, limit[, file]])¶ Print up to limit stack trace entries from the traceback object tb. If limit is omitted or None, all entries are printed. If file is omitted or None, the output goes to sys.stderr; otherwise it should be an open file or file-like get exception message object to receive the output. traceback.print_exception(etype, value, tb[, limit[, file]])¶ Print exception information and up to limit stack trace entries from the traceback tb to file. This differs from print_tb() in the following ways: (1) if tb is not None, it prints a header Traceback (most recent call last):; (2) it prints the exception etype and value after the stack trace; (3) if etype is SyntaxError and value has the appropriate format, it prints the line where the syntax error occurred with a caret indicating the approximate position of the error. traceback.print_exc([limit[, file]])¶ This is a shorthand for print_exception(sys.exc_type, sys.exc_value, sys.exc_traceback, limit, file). (In fact, it uses sys.exc_info() to retrieve the same information in a thread-safe way instead of using the deprecated variables.) traceback.format_exc([limit])¶ This is like print_exc(limit) but returns a string instead of printing to a file. New in version 2.4. traceback.print_last([limit[, file]])¶ This is a shorthand for print_exception(sys.last_type, sys.last_value,
