用python连接数据库SQLite, 就可以形成收集数据,处理数据,存储数据,查询数据的一条龙系统。 1. python基本语法 建立链接 import sqlite3 #载入包 conn = sqlite3.connect('database.sqlite') # 链接数据库 cur = conn.cursor() # 生成指针实例 执行语句 cur.execute('''DROP TABLE IF EXISTS TEST ''') #...
airflow 是能进行数据pipeline的管理,甚至是可以当做更高级的cron job 来使用。现在一般的大厂都说自己的数据处理是ETL,美其名曰 data pipeline,可能跟google倡导的有关。airbnb的airflow是用python写的,它能进行工作流的调度,提供更可靠的流程,而且它还有自带的UI(可能是跟airbnb设计主导有关)。话不多说,先放两...

- Python的sklearn.pipeline.Pipeline()函数可以把多个“处理数据的节点”按顺序打包在一起,数据在前一个节点处理之后的结果,转到下一个节点处理。除了最后一个节点外,其他节点都必须实现'fit()'和'transform()'方法, 最后一个节点需要实现fit()方法即可。当训练样本数据送进Pipeline进行处理时, 它会逐个调用节点的...
