Solve the following python programming problem given the following code:
@ v2_only () 
def test_network_mode_from_container(self) : 
    def get_project() : 
        return Project.from_config (name = 'composetest', config_data = build_config ({ 
            'version' : V2_0, 
            'services' : { 
                'web' : { 
                    'image' : 'busybox:latest', 
                    'network_mode' : 'container:composetest_net_container', 
}, 
}, 
}), client = self.client) 
with pytest.raises (ConfigurationError) as excinfo : 
        get_project () 
assert ("container 'composetest_net_container' which does not exist" in excinfo.exconly ()) 
    net_container = Container.create (excinfo.client, image = 'busybox:latest', name = 'composetest_net_container', command = 'top', labels = { 
        LABEL_PROJECT : 'composetest', 
}) 
    net_container.start () 
    project = get_project () 
    project.up () 
    web = project.get_service ('web') 
    self.assertEqual (web.network_mode.mode, ('container:' + net_container.id)) 

    
    

    Fix the buggy line: net_container = Container.create (excinfo.client, image = 'busybox:latest', name = 'composetest_net_container', command = 'top', labels = {
assistant
#Here is Python code to fix the buggy line: net_container = Container.
