为了提高可读性和最佳实践，请尝试以下方法:

python - 2 - isce ()

import types
if isinstance(lst, types.ListType) or isinstance(lst, types.TupleType):
    # Do something

Python3 - isinstance（）

import typing
if isinstance(lst, typing.List) or isinstance(lst, typing.Tuple):
    # Do something

希望能有所帮助。

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

str对象没有__iter__属性

>>> hasattr('', '__iter__')
False 

你可以检查一下

assert hasattr(x, '__iter__')

这也会对任何其他不可迭代对象抛出一个漂亮的AssertionError。

编辑: 正如Tim在评论中提到的，这只适用于python2。X，不是3。X

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。

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

H = "Hello"

if type(H) is list or type(H) is tuple:
    ## Do Something.
else
    ## Do Something.
