如何在 Python 中比较对象的类型?

问题描述

基本上我想这样做:

obj = 'str'
type ( obj ) == string

我试过了:

type ( obj ) == type ( string )

它没有用.

另外，其他类型呢?例如，我无法复制 NoneType.

Also, what about the other types? For example, I couldn't replicate NoneType.

解决方案

isinstance()

在您的情况下， isinstance("this is a string", str) 将返回 True.

In your case, isinstance("this is a string", str) will return True.
