python except异常处理之后不退出,解决异常继续执行的实现

def run_analyze():
    sleep(2)
    berror = True
    temp = {}
    while berror == True:
      with open(self.filepath, 'r') as f:
      global filename,filescore,filesize,filebehavior,filestrings
        try:
          temp = json.loads(f.read())
          berror = False
        except:#KeyError, VauleError
          print "analyze report is creating,please wait a moment..."
          f.close()
          sleep(5)
          berror = True
          pass
    filescore = float(temp['info']['score'])
    print ("filescore:%d" %filescore)
