Python object() Function

Returns a featureless object.

Syntax

object()

The object has all the methods that are common to all instances of Python class, but because object does not have a __dict__ so you can't assign attributes (properties or methods) to an instance of the new object. One of the purposes for creating a featureless object is to create a unique object that can be tested as a "sentinel" value, for example when using the iter() function.

Example

class Counter():
    n = 0
    sentinel = object()

    def count(self):
        if (self.n == 5):
            return self.sentinel

        self.n += 1
        return self.n - 1

counter = Counter()
for item in iter(counter.count, counter.sentinel):
    print(item)
