如何检查变量的类型是否为字符串? [英] How to check if type of a variable is string?

问题描述

有没有办法检查python中变量的类型是否为string，例如:

Is there a way to check if the type of a variable in python is a string, like:

isinstance(x,int);

对于整数值?

推荐答案

在 Python 2.x 中，你会这样做

In Python 2.x, you would do

isinstance(s, basestring)

basestring 是抽象超类str 和 unicode.可以用来测试一个对象是str还是unicode的实例.

basestring is the abstract superclass of str and unicode. It can be used to test whether an object is an instance of str or unicode.

在 Python 3.x 中，正确的测试是

In Python 3.x, the correct test is

isinstance(s, str)

bytes 类在 Python 3 中不被视为字符串类型.

The bytes class isn't considered a string type in Python 3.
