Bug #115143, was updated on 2000-Sep-22 14:57
Here is a current snapshot of the bug.

Project: Python
Category: Parser/Compiler
Status: Open
Resolution: None
Bug Group: None
Priority: 4
Summary: Python sometimes complains about continue in an except

Details: If a continue statement occurs in the second try/except
statement nested within another try statement, it complains
about the second continue.  For example, this code generates a SyntaxError:

    for i in range(10):
        try:
            try:
                pass
            except:
                continue
            try:
                pass
            except:
                continue
        except:
            pass

while this is fine:

    for i in range(10):
        try:
            pass
        except:
            continue
        try:
            pass
        except:
            continue

This problem exists in both 1.5.2 and 2.0b1.

A workaround is to raise "continue" from the inner 
try/except statements and catch it in the outer try/except:

    for i in range(10):
        try:
            try:
                pass
            except:
                raise "continue"
            try:
                pass
            except:
                raise "continue"
        except "continue":
            continue
        except:
            pass
