我必須.format使用python. 我正在使用以下代碼，但它不能按預(yù)期工作。alarm_tables = ["treevashialarm","treekhopolialarm","treetalegaonalarm"]alarm_types = ['As%%','Sd%%','Multi%%']這是我的查詢：query_types = "SELECT \"alarmSeverity\", COUNT(*) FROM " + "'{0}'" + " WHERE isparent = true and eventdate+eventtime BETWEEN TIMESTAMP " + "'{1}" + "T18:30:00.000Z' " + " and TIMESTAMP " + "'{2}" + "T18:29:59.999Z' " + "and eventtype like '{3}' group by \"alarmSeverity\""我正在使用如下格式選項(xiàng)：for i in alarm_tables:    for j in alarm_types:        query_types.format(i,'2019-10-01','2019-10-02',j)        print(query_types)我得到如下輸出：SELECT "alarmSeverity", COUNT(*) FROM '{0}' WHERE isparent = true and eventdate+eventtime BETWEEN TIMESTAMP '{1}T18:30:00.000Z'  and TIMESTAMP '{2}T18:29:59.999Z' and eventtype like '{3}' group by "alarmSeverity"我的預(yù)期輸出之一如下：SELECT "alarmSeverity", COUNT(*) FROM treevashialarm WHERE isparent = true and eventdate+eventtime BETWEEN TIMESTAMP '2019-10-09T18:30:00.000Z' AND TIMESTAMP '2019-10-10T18:29:59.999Z' and eventtype like 'As%' group by "alarmSeverity";我怎樣才能得到想要的。output為什么format不工作。是否有解決方法。也不工作。它在隨機(jī)時(shí)間for loop給出。random output任何幫助表示贊賞！
