Solve the following python programming problem given the following code:
def interpolate_environment_variables(config, section, environment) : 
    def process_item(name, config_dict) : 
        return dict (((key, interpolate_value (name, key, val, section, environment)) for (key, val) in (config_dict or { 
            
}).items ())) 
return dict (((name, process_item (environment, (config_dict or { 
        
}))) for (name, config_dict) in config.items ())) 

    
    

    Fix the buggy line: return dict (((name, process_item (environment, (config_dict or {
assistant
#Here is Python program to fix the buggy line: return dict (((name, process_item (environment, (config_dict or {

return dict (((name, process_item (name, (config_dict or {
