我需要按名称排序并在Python中重写“customer_data”。请你帮忙。
我试过下面的代码，但没有工作。

def sort_by_key(self, list):
        return list['name']
    def sort_customer_data(self,updated_customer_data):
        #sorted_list = sorted(updated_customer_data['customer_data'], key=lambda x: x['name'])
        #sorted_dict = dict(sorted(updated_customer_data['customer_data'].items(), key=lambda item: item))
        sorted_list = sorted(updated_customer_data,key=self.sort_by_key)
        print(sorted(updated_customer_data, key=self.sort_by_key))
        return output.write_file(appendFile, sorted_list)
