Solve the following python programming problem given the following code:
def __init__(self, filename_or_stream, tolerant = False) : 
    ' File can be either a filename or stream/file object.' 
    nodes = { 
        
} 
    ways = { 
        
} 
    superself = self 
    class OSMHandler (xml.sax.ContentHandler) : 
        @ classmethod 
        def setDocumentLocator(self, loc) : 
            pass 
@ classmethod 
        def startDocument(self) : 
            pass 
@ classmethod 
        def endDocument(self) : 
            pass 
@ classmethod 
        def startElement(self, name, attrs) : 
            if (name == 'node') : 
                self.currElem = Node (attrs ['id'], float (attrs ['lon']), float (attrs ['lat'])) 
else : 
                if (name == 'way') :

                        self.currElem.tags [attrs ['k']] = attrs ['v'] 
else : 
                        if (name == 'nd') : 
                            self.currElem.nd_ids.append (attrs ['ref']) 
@ classmethod 
        def endElement(self, name) : 
            if (name == 'node') : 
                nodes [self.currElem.id] = self.currElem

                if (name == 'way') : 
                    ways [self.currElem.id] = self.currElem

    self.ways = ways 
    node_histogram = dict.fromkeys (self.nodes.keys (), 0) 
    todel = [] 
    for way in self.ways.values () : 
        if (len (way.nd_ids) < 2) : 
            todel.append (way.id) 
for way_id in todel : 
        del self.ways [way_id] 
for way in self.ways.values () : 
        for node in way.nd_ids : 
            try : 
                node_histogram [node] += 1 
except KeyError : 
                node_histogram [node] = 1 
new_ways = {

    for (id, way) in self.ways.items () : 
        split_ways = way.split (node_histogram)

    Fix the buggy line: self.ways = tolerant

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

self.ways = new_ways
