def readfile(filename): 
  with open(filename,'r') as f: 
    for line in f.readlines(): 
      linestr = line.strip() 
      print linestr 
      linestrlist = linestr.split("\t") 
      print linestrlist 
      linelist = map(int,linestrlist)# 方法一 
      # linelist = [int(i) for i in linestrlist] # 方法二 
      print linelist
