没有仔细看,不过下面这两句,推荐看看os.path模块里面的函数,可能就不用针对linux和win分别设定不同的分隔符了 引用  
#config vars
systempathchr="/" #路径分割符,*nix用"/" win32用"\\"  
看到代码里面是用在得到文件名的,可以试试os.path.basename活着os.path.split了 
 
复制代码 代码如下:

 >>> import os.path 
  >>> os.path.basename("c:\\test\\aa.txt") 
  'aa.txt' 
  >>> os.path.split("c:\\test\\aa.txt") 
  ('c:\\test', 'aa.txt') 
  >>> os.path.split("c:\\test\\aa.txt")[-1] 
  'aa.txt' 
  >>> os.path.basename("/home/test/aa.txt") 
  'aa.txt' 
  >>> os.path.split("/home/test/aa.txt") 
  ('/home/test', 'aa.txt') 
  >>> os.path.basename("/home/test/aa.txt") 
  'aa.txt'
