我想將python變量結果保存到文件

Question

當這個文件運行時給出相應的輸出值爲;

# test BLE Scanning software 
# jcs 6/8/2014 


import MySQLdb as my 
import blescan 
import sys 


import bluetooth._bluetooth as bluez 

dev_id = 0 

db = my.connect(host="localhost", 
user="root", 
passwd="root", 
db="test" 
) 

cursor = db.cursor() 

try: 
    sock = bluez.hci_open_dev(dev_id) 
    print "ble thread started" 

except: 
    print "error accessing bluetooth device..." 
     sys.exit(1) 

blescan.hci_le_set_scan_parameters(sock) 
blescan.hci_enable_le_scan(sock) 




while True: 
    returnedList = blescan.parse_events(sock, 10) 
    print "----------" 
    for beacon in returnedList: 

     print beacon 


sql = "insert into beacon VALUES(null, '%s')" % \ 
(beacon) 

number_of_rows = cursor.execute(sql) 
db.commit() 

db.close() 

我想存儲在一個文本文件中

cf:68:cc:c7:33:10,b9407f30f5f8466eaff925556b57fe6d,13072,52423,-74,-78

dd:5d:d3:35:09:dd,8aefb0316c32486f825be26fa193487d,1,1,-64,-77 

等輸出......然後寫在文本文件中的這些值存儲。對於文本文件，是否可以生成文本文件作爲腳本的一部分？由於

試試這個爲你的循環

while True: 
    returnedList = blescan.parse_events(sock, 10) 
    print "----------" 
    f = open('bluez.txt', 'a+') 
    for beacon in returnedList: 
     print beacon 
     f.write(','.join(beacon)+'\n') 
    f.close() 

編輯：現在追加模式

，如果你想要的是將數據存儲在文件中，這樣你就可以打開它後，最簡單的方法是使用在Pickle（或cPickle）模塊 類似：

import cPickle 

#store the data in file 

with open('/path/to/file.txt', 'wb') as f: 
    cPickle.dump(returnedList, f) 

#to read the data 

loaded_returnedList = cPickle.load(open('/path/to/file.txt')) 

print loaded_returnedList == returnedList # Prints True 

現在如果你想要的是存儲可視化存儲中的數據（可是在Excel中後打開它），在csv模塊是你

import csv 

with open('/path/to/file', 'w') as f: 
    writer = csv.writer(f) 

    for beacon in returnedList: 
     writer.writerow(beacon)
