Insert values to the oracle table using python cx_oracle Session Pool

Can any one help how to insert a single row into the oracle table using the python cx_oracle Session Pool? I am seeing some issue with the below code.

Type error: expecting string or object
Name Null? Type        
---- ----- ------------
ID         NUMBER(38)  
NAME       VARCHAR2(30)

def connections():
    pool = cx_Oracle.SessionPool(user='system',password='oracle',dsn='localhost/orcl', min=5, max=5)
    connection = pool.acquire()
    cur = connection.cursor()

    return cur


def update_table(cursor):
    rows=[(2,"KRR")]
    sql=("insert into exm(id,name) values(:1, :2)", rows)
    cursor.execute(sql)
