Solve the following python programming problem given the following code:
@ staticmethod 
def build(capabilities, device_handler) : 
    "Given a list of capability URI's returns <hello> message XML string" 
    if device_handler : 
        xml_namespace_kwargs = { 
            'nsmap' : device_handler.get_xml_base_namespace_dict (), 
} 
else : 
        xml_namespace_kwargs = { 
            
} 
hello = new_ele ('hello', ** xml_namespace_kwargs) 
    caps = sub_ele (hello, 'capabilities') 
    def fun(uri) : 
        sub_ele (caps, 'capability').text = uri 
if (sys.version < '3') : 
        map (fun, hello) 
else : 
        list (map (fun, capabilities)) 
return to_xml (hello) 

    
    

    Fix the buggy line: map (fun, hello)
