Solve the following python programming problem given the following code:
def _SetValues(self, values) : 
    "Set values from supplied dictionary or list.

    Args:
      values: A Row, dict indexed by column name, or list.

    Raises:
      TypeError: Argument is not a list or dict, or list is not equal row
      length or dictionary keys don't match.
    " 
    def _ToStr(value) : 
        'Convert individul list entries to string.' 
        if isinstance (value, (list, tuple)) : 
            result = [] 
            for val in value : 
                result.append (str (val)) 
return result 
else : 
            return str (value) 
if isinstance (values, Row) : 
        if (self._keys != values.header) : 
            raise TypeError ('Attempt to append row with mismatched header.') 
self._values = copy.deepcopy (values.values) 
else : 
        if isinstance (values, dict) : 
            for key in self._keys : 
                if (key not in values) : 
                    raise TypeError ('Dictionary key mismatch with row.') 
for key in self._keys : 
                self [index] = _ToStr (values [key]) 
else : 
            if (isinstance (values, list) or isinstance (values, tuple)) : 
                if (len (values) != len (self._values)) : 
                    raise TypeError ('Supplied list length != row length') 
for (index, value) in enumerate (values) : 
                    self._values [index] = _ToStr (value) 
else : 
                raise TypeError ('Supplied argument must be Row, dict or list, not %s', type (values))

#Here is Python code to fix the buggy line: self [index] = _ToStr (values [key])
.

self [key] = _ToStr (values [key])
