python 格式化向sql语句输出元组

 1 results = ((1,2,3),(4,5,6))
 2 #因为hive insert 要求values 格式为   insert overwrite table term_dept_top_backup111 values(),()()
 3 #所以我增加的其他代码是为了去除外面的“()”
 4 n = 0
 5 sql = "insert overwrite table term_dept_top_backup111 values "
 6 for row in results:
 7     n = n + 1
 8     if n != len(results)+1:
 9         sql = sql + "{}"
10     sql = sql.format(row)
11     if n != len(results):
12         sql = sql +‘,‘
