Python standard library: built-in function id (object), pythonobject

Python standard library: built-in function id (object), pythonobject

This function is the identifier of the returned object. The identifier type is an integer. In the same time, all object identifiers are unique, objects with different lifecycles may have the same identifier. For example, after object A is created, object A is deleted and object B is created. Object A and object B may have the same identifier. The implementation algorithm in CPython directly returns the memory address of the object.

Example:

# Id () name1 = 'abc' name2 = 'cde' print (id (name1) print (id (name2) print (id ([])

The output is as follows:

5472640

36108384

36127048
