Can u explain about this code? , i did'nt understand about this code

Question

x=11
print (id(x))
x=x+1
print (id(x))

Answer 1

id(obj)

returns the unique identity for object.
cpython uses the memory address of the object

when you initialized x = 11

Python creates object inside memory with value 11 and x refers to it

x = x + 1

here python creates another object 11 + 1 = 12 now x refers to another object and previous object get cleared by garbage collector.

Answer 2

garbage collector is a program which free up the memory by removing dead objects

whenever we create object python keeps count on it
when count is 0 garbage collector get invoked and removes the object when their is no reference to that object .

Answer 3
