Python standard library: Built-in function ID (object)

This function is the identifier of the object that returns the objects, the identifier type is an integer, and the identifiers of all objects are unique at the same time, if the objects in different lifecycles have the same identifier. For example, after creating object A, delete a, and then create object B, Object a and object B may have the same identifier. the implementation algorithm in CPython is the memory address where the object is directly returned.

Example:

#id () name1 = ' abc ' name2 = ' CDE ' Print (ID (name1)) print (ID (name2)) print (ID ([]))

The resulting output is as follows:

5472640
