Python setattr() Function
Sets the attribute of an object. The attribute must have been initialized in the class.
setattr(object, name, value)
||Required. The object for which the attribute will be set. This can be any type.|
||Required. The name of the attribute as a string value.|
||Required. The value to set. This can be any type.|
class MyObject def __init__(self): self.x = 10 object = MyObject() setattr(object, 'x', 20)
While normally one just assigns a value to an attribute, for example
object.x = 10. In meta-programming, however, it can is often useful to be able to
set an attribute by its name. This technique can be used, for example, to map JSON data or
records from a database to a Python object.
There are many Python libraries that do this already, so there is no reason to write your own unless you have some custom requirements.
