Solve the following python programming problem given the following code:
def _analyze_line(self, linenum) : 
    '
        Colorize a given line.
        ' 
    self._clear_tags (linenum) 
    line = self._textwidget.get ((repr (linenum) + '.0'), (repr (self) + '.end')) 
    if CFGEditor._PRODUCTION_RE.match (line) : 
        def analyze_token(match, self = self, linenum = linenum) : 
            self._analyze_token (match, linenum) 
            return '' 
CFGEditor._TOKEN_RE.sub (analyze_token, line) 
else : 
        if (line.strip () != '') : 
            self._mark_error (linenum, line) 

    
    

    Fix the buggy line: line = self._textwidget.get ((repr (linenum) + '.0'), (repr (self) + '.end'))

#Here is Python code to fix the buggy line: line = self.

line = self._textwidget.get ((repr (linenum) + '.0'), (repr (linenum) + '.end'))
