Solve the following python programming problem given the following code:
def __init__(self, default, * options, **kwargs) : 
    self.default = default 
    self.all = ((default,) + convert) 
    for val in self.all : 
        if (not isinstance (val, string_types)) : 
            raise ValueError ('Valid values for an EnumStr parameter should be strings', val, type (val)) 
convert = kwargs.get ('convert', None) 
    def filter(val) : 
        if convert : 
            val = convert (val) 
if (val in self.all) : 
            return val 
else : 
            raise ValueError (('Invalid value ("%s") for configuration variable "%s". Valid options are %s' % (val, self.fullname, self.all))) 
over = kwargs.get ('allow_override', True) 
    super (EnumStr, self).__init__ (default, filter, over) 

    
    

    Fix the buggy line: self.all = ((default,) + convert)

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

self.all = ((default,) + options)
