盯着看了半天还是没找到哪里处错了，烦请大家帮帮忙，看看是哪里出错了。谢谢！

[mw_shl_code=python,true]try:
    f = open('services_pids.txt')
except IOError,mes:
    print "%s IOError: %s"%(timestr , mes)
    services_pids = {}
else:
    services_pids = eval(f.read())
    f.close()
[/mw_shl_code]

我把这段删掉，改为 services_pids ={}
就没报错了。
但还是没找到怎么错了…………………………

晕死…… 将f=open('services_pids.txt') 的变量f改下名字就好了
难道是因为和下面的start方法里的重复了……？

可能是编辑器的问题，楼主是否使用Python自己的编辑器

可能作用域的原因。

总算找到原因了 是eval函数的问题。要将从文件读的数据转换成相应的格式，但是如果文件是空的就会出错。

改成下面的就OK了。

    f = open('services_pids.txt')

        print "%s the file services_pids.txt is wrong"%timestr
