You can use the id function and type function to get different pieces of information about an object.

Work Step by Step

$id:$ The id for the object is automatically assigned a unique integer by Python when the program is executed. The id for the object will not be changed during the execution of the program. However, Python may assign a different id every time the program is executed $type:$ The type for the object is determined by Python according to the value of the object. Line 2 displays the id for a number object n, line 3 shows the id Python has assigned for the object, and its type is displayed in line 4. $Note:$ The $id$ and $type$ functions are rarely used in programming, but they are good tools for learning more about objects.
