Would it also understand line continuations using parentheses ( the more common style)? On Tuesday, April 30, 2013, Antoine Pitrou wrote:

Instead I would expect:
Traceback (most recent call last): File "foo.py", line 1, in <module> assert \ 1 == 0, \ "error" AssertionError: error
Not sure how easy this is to implement but I think it would be a good enhancement. Thoughts?
Very dubious idea, for multiple reasons given on the issue.
It seems this is already tracked in http://bugs.python.org/issue12458
For your example, the OP of that issue would replace the line '"error"' with 'assert', which would not be helpful at all. If your statement was
assert some_fairly_long_expression_with_calls ==\ something_else, "error"
then is would not be clear that backing up would be helpful.
Perhaps you've missed that Giampaolo's suggestion was to print the *entire* statement, not just one line chosen at random?
There's one thing this proposal would make more difficult, which is machine-processing of tracebacks. Otherwise it does look better to me.

Antoine.
