Python3.3 django error handling "sre_constants.error: nothing to repeat"

After python3.3, The multiline Regular Expression matching seems to have been modified. It cannot match a multi-line regular expression with non-escape characters.

The following error is reported:

>>>

As prompted, we need to modify the value assignment of locatestarttagend_tolerant in row 56th of the "C: \ Python33 \ Lib \ html \ parser. py" file.

The modification method is to convert the original multi-line escape character into one line.

I have a problem with the incorrect understanding. It should be due to the regular expression writing problem. It's late, and another day is working on it.
