Location of integer object storage in Python

The Python integer object is stored in a different location, some of which are stored in a store, while others create space when used.

To say the reason for this sentence, you can look at the following code:

A = 5
b = 5
A is B # True

A = 500
b = 500
A is B # False

As the above code shows, the integer 5 is always there, and the integer 500 is not always there.

So what are the integers that have been stored?

A, b, c = 0, 0, 0
While A is B:
i + = 1
A, b = Int (str (i)), int (str (i))
Else
Print (i) # printing 257

As you know, a nonnegative integer less than or equal to 256 (2**8) is stored all the time.

A =-1
b =-1
A is B # False

Negative numbers are not always stored.
