Solve the following python programming problem given the following code:
def reformat_text(self) : 
    text = self.toPlainText () 
    if (not (':' in text)) : 
        return 
pattern = '[^\\s]*:[^\\s]*' 
    def format_components(m) : 
        component = m.group (0) 
        if (component in self.word_list) : 
            return (("<font color='#0072B2'><b>" + component) + '</b></font> ') 
else : 
            return (("<font color='#D55E00'><b>" + component) + '</b></font> ') 
html = re.sub (text, format_components, text) 
    tc = self.textCursor () 
    pos = tc.position () 
    self.setHtml (html) 
    text = self.toPlainText () 
    pos = min (pos, len (text)) 
    tc.setPosition (pos) 
    self.setTextCursor (tc) 
    self.setAlignment (Qt.AlignCenter) 

    
    

    Fix the buggy line: html = re.sub (text, format_components, text)

#Here is Python program to fix the buggy line: html = re.

html = re.sub (pattern, format_components, text)
