Python 将元组从pandas导出到sql

我在jupyter笔记本中工作，我想将元组导出到sql（在where条件下）。但是id不起作用

numb = ('1','2', '3')


query =  """ SELECT *
              from table
              where table.number in numb """

conn = psycopg2.connect(dbname='dbname', user='user', 
                        password='pass', host='host' ,port ='port')

但这是有效的

query =  """ SELECT *
              from table
              where table.number in ('1','2', '3') """

conn = psycopg2.connect(dbname='dbname', user='user', 
                        password='pass', host='host' ,port ='port')

您差一英寸就错过了，下面的代码应该可以工作：

numb = ('1','2', '3')


query =  f""" SELECT *
              from table
              where table.number in {numb} """

conn = psycopg2.connect(dbname='dbname', user='user', 
                        password='pass', host='host' ,port ='port')

或

打印（查询）

的输出：

请注意，还有其他几种方法。你需要看看python

numb = ('1','2', '3')


query =  """ SELECT *
              from table
              where table.number in {} """.format(numb)

conn = psycopg2.connect(dbname='dbname', user='user',
                        password='pass', host='host' ,port ='port')

 SELECT *
              from table
              where table.number in ('1', '2', '3')
