当比较两个对象类型时,请考虑使用 isinstance() 而不是 type,因为 isinstance() 判断一个对象是否为另一个对象的子类是 true。考虑这样一个场景:如果传递的数据结构是dict 的子类,比如 orderdict。type() 对于特定类型的数据结构将失败;然而,isinstance() 可以将其识别出它是 dict 的子类。
They’re commonly used for output that contains raw HTML that is intended to be interpreted as-is on the client side. Internally, these strings are of type SafeString. You can test for them using code like: from django.utils.safestring import SafeString if isinstance(value, SafeString): #...
To determine the type of a variable, you can simply use either type() or isinstance() methods, both methods are built-in methods of the Python standard library. In this tutorial, we will be learning about these methods, and how can we use these methods to determine the type of a ...
