Python 3 equivalent of HTMLParseError?

I just wanted to know if there is any Python 3 equivalent of the HTMLParseError as in Python 2. HTMLParseError seems to have been deprecated from Python 3.3 onward and removed in Python 3.5.

Is there any way to catch the HTMLParseError in Python versions > 3.5?

Following is a traceback I receive:

  File "/opt/Projects/WAFToast/main.py", line 12, in <module>
    HTMLParseError = html.parser.HTMLParseError
AttributeError: module 'html.parser' has no attribute 'HTMLParseError'

Doing some Googling around, I found the same issue being fixed with a patch as below which imho is not a wholesome solution:

try:
    from html.parser import HTMLParseError
except ImportError:  # Python 3.5+
    class HTMLParseError(Exception):
        pass

It would be really great if someone could point out the necessary I am missing. =)

The docs say:

Deprecated since version 3.3, will be removed in version 3.5: This exception has been deprecated because it’s never raised by the parser (when the default non-strict mode is used).

It was removed because nothing raised it unless the (presumably) little used strict mode is used, so a question must be asked: "are you using the strict mode?"

If you are not, you can safely remove the import and the code that catches it.

If you are, check what exception is raised instead (if at all), and import it instead.

If you use strict mode and have to support both versions of Python, you can do something along the lines of

try:
    from html.parser import HTMLParseError as ParseError
except ImportError:  # Python 3.5+
    from html.parser import NewTypeOfFancyException as ParseError

then use except ParseError where applicable.
