Question

python读取数据库，怎么把列名显示出来?

Answer 1

def query(self, sql):
connect = self.connect()
cur = connect.cursor()
cur.execute(sql)
index = cur.description
result = []
for res in cur.fetchall():
row = {}
for i in range(len(index)-1):
row[index[i][0]] = res[i]
result.append(row)
connect.close()
return result
这个方法返回查询结果就是带字段名的{‘字段名’：‘值’}
