In Language Ref section 7 "Compound Statements": http://docs.python.org/release/3.1.3/reference/compound_stmts.html there's a footnote regarding what happens to unhandled exceptions in a try-except statement: [1] The exception is propagated to the invocation stack only if there is no *finally* clause that negates the exception. This is very unclearly worded, especially since the reader in need of this footnote is probably familiar with the *except* clause being the one to "negate" an exception, and may well think this footnote is in error. This footnote could provide a more convincing explanation: [1] The exception is propagated to the invocation stack unless there is a finally clause which happens to raise another exception. That new exception causes the old exception to be lost.

Sometimes we use the patch keyword for doc issues where someone has suggested a specific new wording but not generated an actual patch. That seems to be the case here.

Just to make explicit what's happening: >>> try: ... try: ... raise TypeError() ... finally: ... raise ValueError() ... except TypeError as e: ... print('mmm') ... Traceback (most recent call last): File "", line 3, in TypeError During handling of the above exception, another exception occurred: Traceback (most recent call last): File "", line 5, in ValueError while >>> try: ... try: ... raise TypeError() ... finally: ... raise ValueError() ... except ValueError as e: ... print ('mmm') ... mmm
