Python getattr

Python getattr() 函数 Python 内置函数描述 getattr() 函数用于返回一个对象属性值。语法 getattr 语法： getattr(object, name[, default]) 参数 object -- 对象。 name -- 字符串，对象属性。 default -- 默认返回值，如果不提供该参数，在没有对应属性时，将触发 AttributeError。

Python getattr () Method The getattr () method returns the value of the attribute of an object. If the named attribute does not exist, default is returned if provided, otherwise AttributeError is raised. Another use of getattr () in implementing a switch statement in Python. It uses both reflection to get the case type. Python getattr () Function The python getattr () function returns the value of a named attribute of an object.

Currently, the types of attributes that can be displayed are: numeric attributes; string attributes; matrix attributes; numeric compound attributes (whose children are all numeric) vector "d.this_does_not_exist" attempts to access the "this_does_not_exist" attribute of the class Dummy and therefore our custom defined method getattr is called returning the capitalized version of method name. Note that getattr has two arguments, "self" represents instance of the class and attr is the attribute name, in this case "this-does_not_exist" 4.4.2. getattr As a Dispatcher You already know that Python functions are objects. What you don't know is that you can get a reference to a function without knowing its name until run-time, by using the getattr function. Example 4.10.

Python expert Martin Aspeli identifies when Python is the right choice, and when another language mi Unlike PHP, the Python programming language does not have an "echo" function that produces a string of output information. Instead, Python uses another similar statement called "print" to produce the same effect. Unlike PHP, the Python prog Variants of getattr()¶.

The syntax of getattr () method is: The getattr () is a built-in function in Python that is used to access/return the value of a specified attribute of an object. We can access the value of an attribute by the command: object_name.attribute_name too. So, what makes getattr () different? Python getattr is used to get an object attribute value, and if no attribute of that object is identified, the default value is returned.

Conclusion. In this Python Tutorial, we have learnt the syntax of Python getattr() builtin function, and also learned how to use this function, with the help of Python example programs. The setattr () function sets the value of the attribute of an object. The syntax of the setattr () function is: setattr (object, name, value) If you want to get the attribute of an object, use getattr (). Python hasattr() Function Built-in Functions. Example.

Python getattr is used to get an object attribute value, and if no attribute of that object is identified, the default value is returned. The getattr function takes two parameters, the name of the object and the name of the member data. This particular attribute works the same as we do use dot character.

Bases: object. Tries to emulate the standard Python AttributeError message.
