在使用者中处理生成器异常

您可以在parsefunc中返回记录和异常的元组，并让使用者函数决定如何处理异常：

import randomdef get_record(line):  num = random.randint(0, 3)  if num == 3:    raise Exception("3 means danger")  return linedef parsefunc(stream):  for line in stream:    try:      rec = get_record(line)    except Exception as e:      yield (None, e)    else:      yield (rec, None)if __name__ == '__main__':  with open('temp.txt') as f:    for rec, e in parsefunc(f):      if e:        print "Got an exception %s" % e      else:        print "Got a record %s" % rec
