Python使用pymysql返回字典类型的数据
参考文档链接
https://blog.csdn.net/qq_26003101/article/details/113732615
在默认情况下cursor方法返回的是BaseCursor类型对象，BaseCursor类型对象在执行查询后每条记录的结果以列表(list)表示。如果要返回字典(dict)表示的记录，就要设置cursorclass参数为MySQLdb.cursors.DictCursor类
import pymysql
import time
# 数据库
db = ""
cur = ""
# 现在年月日
today = time.strftime("%Y-%m-%d", time.localtime())
try:
# 数据库配置
config = {
"host": "124.71.18.23",
"port": 3306,
"user": "root",
"password": "Master@test",
"db": 'scrapy',
"charset": "utf8mb4",
"cursorclass": pymysql.cursors.DictCursor
}
db = pymysql.connect(**config)
# 游标
cur = db.cursor()
except:
print("连接数据库失败")
exit(-1)
# 查询今天之后的所有天气数据
def get_day_list(date):
sql_weather_days = "SELECT*FROM weather WHERE date>='" + date + "'"
cur.execute(sql_weather_days)
dayList = cur.fetchall()
print(dayList)
pass
get_day_list(today)
