Usetime.time()¶ You can usetime.time()to create the current time. Then you determine the time before and after the code part you want to measure, and in the end you can subtract the time points to get the elapsed time: importtimestart=time.time()# your code...end=time.time()pr...

elapsed = (time.time() - start) print elapsed, " seconds" cur.close() con.close() 该脚本使用“time”模块测量查询所花的时间。默认值被设置为 100。这导致每次从数据库向 Python 的缓存返回 100 条记录。这就减少了对数据库的“忘返”次数,通常还会降低网络负载并减少数据库服务器上下文切换次数。从数...
