pymysql怎么使用cur.fetchall()和cur.fetchone()

import pymysql,hashlib
結(jié)果：?jiǎn)螚l結(jié)果 {'id': 1, 'name': '打車', 'phone': '132453'}

sql = 'select * from zxj'
def op_mysql(sql,many=True):
 db_info = {'user': 'jxz', 'password': '123456',
  'host': '118*******', 'db': 'jxz', 'port': 3306, 'charset': 'utf8',
  'autocommit': True}
 conn = pymysql.connect(**db_info) # 建立連接
 cur = conn.cursor(pymysql.cursors.DictCursor) # 游標(biāo)
 cur.execute(sql) # 執(zhí)行sql語(yǔ)句，insert 、update 、delete
 if many:
 result = cur.fetchall()
 print('多條',result)
 else:
 result = cur.fetchone() # {''}
 print('dantiao',result)
 cur.close()
 conn.close()
 return result
op_mysql(sql,many=False) # 傳入sql, 默認(rèn)為true
