Unicode string appears as false in isinstance()

As far as I know, the integer value should be checked with isinstance(x, int);.

However, when I wrote isinstance(x,str);, Unicode is not recognized as a string, so I can't do anything.

What should I do?

>>> foo = u"hello"
>>> isinstance(foo, str)
False
>>>

You must be using the Python 2.x version. In python2,

isinstance(s, basestring)

You have to write it like this.

If you search it and write it down for those who come in,

In Python3, there is no basering

isinstance(s,str);

You can use it as
