Python路径定义/ Python 2.7.3

Question

我试图定义一个简单的python路径，但我总是得到一个错误。有人能告诉我如何设置正确的路径吗?我正在做一个树莓派。

下面是不能工作的代码:

import re, os, rrdtool, time, sys

# define pathes to 1-wire sensor data
pathes = "/sys/bus/w1/devices/10-000801ddae93/w1_slave"

和

# insert data into round-robin-database
rrdtool.update(
"%s/temperature.rrd" % (os.path.dirname(os.path.abspath(__file__))),
data)

我得到的错误:

07/27/15 13:21:37 Error reading s :  [Errno 2] No such file or directory: 's'
07/27/15 13:21:39 Error reading y :  [Errno 2] No such file or directory: 'y'
07/27/15 13:21:40 Error reading s :  [Errno 2] No such file or directory: 's'
07/27/15 13:21:41 Error reading / :  [Errno 21] Is a directory: '/'
07/27/15 13:21:42 Error reading b :  [Errno 2] No such file or directory: 'b'
07/27/15 13:21:44 Error reading u :  [Errno 2] No such file or directory: 'u'
07/27/15 13:21:45 Error reading s :  [Errno 2] No such file or directory: 's'
07/27/15 13:21:46 Error reading / :  [Errno 21] Is a directory: '/'
07/27/15 13:21:48 Error reading w :  [Errno 2] No such file or directory: 'w'
07/27/15 13:21:49 Error reading 1 :  [Errno 2] No such file or directory: '1

'等等…

和

Traceback (most recent call last):
  File "/home/pi/python.py", line 39, in <module>
    data)
error: /home/pi/temperature.rrd: found extra data on update argument: U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U:U

我希望你能帮助我。

update()可能需要一个列表类型，或者可以迭代的类型。
