Analysis on the location of integer Object Storage in Python, and python integer

Python integer objects are stored in different locations. Some of them are stored in a certain storage, while others are used to open up space.

For the reason of this sentence, you can look at the following code:

A = 5b = 5a is B # Truea = 500b = 500a is B # False

The code above shows that integer 5 always exists, while integer 500 never exists.

Which integers are stored all the time?

A, B, c = 0, 0, 0 while a is B: I + = 1a, B = int (str (I), int (str (I) else: print (I) # print 257

As we know, non-negative integers smaller than or equal to 256 (2 ** 8) are always stored.

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

Negative numbers are not stored all the time.
