【初學python】使用python連接mysql數據查詢結果並顯示

因為測試工作經常需要與后台數據庫進行數據比較和統計，所以采用python編寫連接數據庫腳本方便測試，提高工作效率，腳本如下（python連接mysql需要引入第三方庫MySQLdb，百度下載安裝)

#-*- coding: utf-8 -*-

import MySQLdb, datetime, time
#code數字含義
code_mean = {10:"開始下載（10）",
				   11:"下載完成（11）",
				   12:"安裝界面（12）",
				   13:"安裝成功（13）",
				   14:"啟動游戲（14）",
				   16:"更新開始（16）"}
#Networktype數字含義
network_type_mean = {1:"3G  網絡",
				     2:"2G  網絡",
					 3:"WIFI網絡"}
#當前測試人員擁有手機
phonelist = {1:"0049990********", 2:"8689430********", 3:"3558680********"}
#當前系統時間
nowtime = (datetime.datetime.fromtimestamp(time.time()).strftime('%Y-%m-%d %H:%M:%S'))
print "當前時間：" + nowtime
today = str(nowtime).split()[0]
#去除日期
HMS = nowtime.split()[1]

print "目前測試人員擁有的手機如下："
print "HTC    ***  ：1"
print "HTC    ****  ：2"
print "HUAWEI ***** ：3"

phont_imei = raw_input("請選擇你要查詢的手機，輸入上列手機對應的數字即可：")
time_start = raw_input("請輸入需要查詢的起始時間（格式如后：" + HMS + "，默認日期為今天）: ")
imei = phonelist[int(phont_imei)]
#查詢開始時間
starttime = datetime.datetime.now()

print "開始連接數據庫......"
try:
	db = MySQLdb.connect(host="***.***.***.***", port=****, user="****", passwd="****", db="****")
	cursor = db.cursor()
	print "數據庫連接成功，開始進行查詢......"
	cursor.execute('''SELECT
	****,
	****,
	****,
	****,
	****
	from ****
	WHERE
	**** =  \'''' + imei + '''\' AND
	**** > \'''' + today + " " + time_start + '''' AND
	**** IN (10, 11, 12,13,14,16)
	ORDER BY
	**** DESC
	''')
	result = cursor.fetchall()
	print "已獲取查詢結果，開始斷開數據庫連接....."
	cursor.close()
	db.close()
except MySQLdb.Error,e:
     print "Mysql Error %d: %s" % (e.args[0], e.args[1])
else:
	print "斷開數據庫連接成功，開始展示查詢結果......"
	if bool(result) != True:
		print "( ⊙ o ⊙ )啊哦，竟然沒有查詢到數據結果，請檢查下查詢時間"
	else:
		#對查詢出的數據進行處理，方便查看
		print ""
		print "++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++"
		i = 0
		for record in result:
			sqldata = result[i]
			time = sqldata[0]
			code = sqldata[1]
			name = sqldata[2]
			networktype = sqldata[4]
			print network_type_mean[int(networktype)] + \
					" " + str(time).split()[1] + \
					" " + code_mean[int(code)] + \
					" " + name
			i += 1
		print "++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++"
#結果展示時間
endtime = datetime.datetime.now()
wast_time = (endtime - starttime).seconds
print "本次查詢總共耗時：" + str(wast_time) + " 秒 " + "查詢手機IMEI：" +  phonelist[int(phont_imei)]

　　目前腳本的缺點是只能進行一次性查詢，之后再進行優化使之能進行多次查詢后再斷開數據庫連接
