Question

我有一个db1表，其中Column1 = Name和Column2 =属性。对于每个Name，最大属性值数= 5.在我的GUI（通过python生成）中，我有5个文本框，根据select语句我打印属性值。我尝试在row_count语句中插入打印结果，但我找不到解决方案，我不知道如何使用row_count作为参数，这意味着如果row_count = 3则打印3结果（为了放它在前三个文本框中），如果1然后是1个结果等，如果rowcount-1 <0，则继续其余代码而不填写其余文本框。我在下面只分离了选择部分。提前谢谢。

     import cx_Oracle
     connstr='SOLVATIO/SOLVATIO@localhost'
     conn = cx_Oracle.connect(connstr)
     curs = conn.cursor()
     curs.execute("select attributes, count(*) from customer_desc group     by attributes")      
     result=curs.fetchall()
     r_count=curs.rowcount
     print("number of:{}".format(r_count))
     if r_count==0:
     print("no rows")
     else:
       print(result[???])->based on r_count i.e if r_count=3, print(result[0]),print(result[1]), print(result[2])
    conn.close()
