Python standard library: Built-in function GetAttr (object, name[, default])

This function implements the Get property of object. Property is represented by name, which is a string of property names. The parameter default is an optional parameter that is returned when the property that gets the object does not exist. Assume that this parameter is not provided. The same time is not found in the object properties, and does not throw an exception attributeerror.

Examples:

#getattr () class Foo:    def __init__ (self):        self.x = +                foo = foo () print (GetAttr (Foo, ' x ')) print (foo.x) Print (GetAttr (foo, ' Y ', 200))

The output results are as follows:
