Solve the following python programming problem given the following code:
def convert_values(self) : 
    'Convert datetimes to a comparable value in an expression.
        ' 
    def stringify(value) : 
        if (self.encoding is not None) : 
            encoder = partial (pprint_thing_encoded, encoding = self.encoding) 
else : 
            encoder = pprint_thing 
return encoder (value) 
(lhs, rhs) = (self.lhs, self.rhs) 
    if (is_term (lhs) and lhs.is_datetime and is_term (rhs) and rhs.isscalar) : 
        v = rhs.value 
        if isinstance (v, (int, float)) : 
            v = stringify (v) 
v = pd.Timestamp (_ensure_decoded (stringify)) 
        if (v.tz is not None) : 
            v = v.tz_convert ('UTC') 
self.rhs.update (v) 
if (is_term (rhs) and rhs.is_datetime and is_term (lhs) and lhs.isscalar) : 
        v = lhs.value 
        if isinstance (v, (int, float)) : 
            v = stringify (v) 
v = pd.Timestamp (_ensure_decoded (v)) 
        if (v.tz is not None) : 
            v = v.tz_convert ('UTC') 
self.lhs.update (v) 

    
    

    Fix the buggy line: v = pd.Timestamp (_ensure_decoded (stringify))
assistant
#Here is Python program to fix the buggy line: v = pd.

v = pd.Timestamp (_ensure_decoded (v))
