我有一个以下代码,用于捕获条形码扫描器的输入.问题在于我想将整个扫描的代码保存在数据库中,但代码的每个字符都在新行上打印:

#!/usr/bin/env python

from evdev import InputDevice, ecodes, list_devices
from select import select

keys = "X^1234567890XXXXqwertzuiopXXXXasdfghjklXXXXXyxcvbnmXXXXXXXXXXXXXXXXXXXXXXX"
dev = InputDevice("/dev/input/event10")

barcode = ""
while True:
    r,w,x = select([dev], [], [])

    for event in dev.read():
        if event.type == 1 and event.value == 1:
             barcode += (keys[event.code])

    print barcode

# sudo ./bar-code-test.py

我是python的新手,所以任何帮助将不胜感激.
