>>> thing = 'foo'
>>> type(thing).__name__ == 'str' or type(thing).__name__ == 'unicode'
True

我是这样做的:

if type(x) == type(str()):

我看过:

hasattr(s, 'endswith') 

s = '123'
issubclass(s.__class__, str)

您可以简单地使用isinstance函数来确保输入数据的格式为字符串或unicode。下面的例子会帮助你更容易理解。

>>> isinstance('my string', str)
True
>>> isinstance(12, str)
False
>>> isinstance('my string', unicode)
False
>>> isinstance(u'my string',  unicode)
True

你可以:

var = 1
if type(var) == int:
   print('your variable is an integer')

or:

var2 = 'this is variable #2'
if type(var2) == str:
    print('your variable is a string')
else:
    print('your variable IS NOT a string')

希望这能有所帮助!
