我在tensorflow中找到了这样一个名为is_sequence的函数。

def is_sequence(seq):
  """Returns a true if its input is a collections.Sequence (except strings).
  Args:
    seq: an input sequence.
  Returns:
    True if the sequence is a not a string and is a collections.Sequence.
  """
  return (isinstance(seq, collections.Sequence)
and not isinstance(seq, six.string_types))

我已经核实了，它符合你的需求。

assert (type(lst) == list) | (type(lst) == tuple), "Not a valid lst type, cannot be string"

我在测试用例中这样做。

def assertIsIterable(self, item):
    #add types here you don't want to mistake as iterables
    if isinstance(item, basestring): 
        raise AssertionError("type %s is not iterable" % type(item))

    #Fake an iteration.
    try:
        for x in item:
            break;
    except TypeError:
        raise AssertionError("type %s is not iterable" % type(item))

没有在发电机上进行测试，我认为如果通过发电机，你会在下一次“屈服”时留下，这可能会把下游的事情搞砸。不过，这是一个unittest

带有PHP风格的Python:

def is_array(var):
    return isinstance(var, (list, tuple))

我倾向于这样做(如果我真的，真的必须这么做的话):

for i in some_var:
   if type(i) == type(list()):
       #do something with a list
   elif type(i) == type(tuple()):
       #do something with a tuple
   elif type(i) == type(str()):
       #here's your string

在python中>3.6
