如何使用python编程创建kafka的topic

You can programmatically create topics either using  kafka-python  or  confluent_kafka  client which is a lightweight wrapper around librdkafka.

Using  kafka-python

              
                
                  from
                
                
                   kafka
                
                
                  .
                
                
                  admin 
                
                
                  import
                
                
                  KafkaAdminClient

                  NewTopic
