使用下面的代码读取mysql数据时出现TypeError: tuple indices must be integers or slices, not str错误

    conn = pymysql.connect(host=dbhost, user=dbuser, passwd=dbpasswd, db=dbname)
    while True:
        cur = conn.cursor()
        cur.execute("SELECT * from  radardevices where status=1")
        row_headers = [x[0] for x in cur.description]
        rows = cur.fetchall()
        for row in rows:
            print(row["macaddress"])
        cur.close()
        time.sleep(1)
    conn.close()

conn = pymysql.connect(host=dbhost, user=dbuser, passwd=dbpasswd, db=dbname)

while True:

cur = conn.cursor()

cur.execute("SELECT * from radardevices where status=1")

row_headers = [x[0] for x in cur.description]

rows = cur.fetchall()

for row in rows:

print(row["macaddress"])

cur.close()

time.sleep(1)

conn.close()

获取cursor时未指定cursor类型，默认使用tuple类型返回，将cur = conn.cursor()这一行修改为如下就可以了

cur = conn.cursor(cursor=pymysql.cursors.DictCursor)

1	cur = conn.cursor(cursor=pymysql.cursors.DictCursor)
