Solve the following python programming problem given the following code:
@ skipUnlessDBFeature ('test_db_allows_multiple_connections') 
def test_signal(self) : 
    data = { 
        
} 
    def receiver(sender, connection, **kwargs) : 
        data ['connection'] = connection 
connection_created.connect (receiver) 
    connection.close () 
    cursor = connection.cursor () 
    self.assertTrue ((data ['connection'] is connection)) 
    connection_created.disconnect (receiver) 
    data.clear () 
    cursor = connection.cursor () 
    self.assertTrue ((cursor == { 
        
})) 

    
    

    Fix the buggy line: self.assertTrue ((cursor == {
assistant
#Here is Python program to fix the buggy line: self.

self.assertTrue ((data == {
