py: Implement support for "except Exception as var" clause. For this, needed to implement DELETE_NAME bytecode (because var bound in except clause is automatically deleted at its end). http://docs.python.org/3/reference/compound_stmts.html#except : "When an exception has been assigned using as target, it is cleared at the end of the except clause." 2014-03-23 19:19:02 +00:00			`try:`

tests: Modify tests that print repr of an exception with 1 arg. In Python 3.7 the behaviour of repr() of an exception with one argument changed: it no longer prints a trailing comma in the argument list. See https://bugs.python.org/issue30399 This patch modifies tests that rely on this behaviour to not rely on it. And the python34.py test is updated to include a test for this behaviour with a .exp file. 2018-08-17 05:46:04 +00:00			`print(type(e), e.args)`
