The principle of resident Mechanism of python string

This article mainly introduces "the principle of resident mechanism of python string". In daily operation, I believe that many people have doubts about the principle of resident mechanism of python string. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "principle of resident mechanism of python string". Next, please follow the editor to study!

1. Only one same and immutable string is saved, and different values are stored in the pool of the string.

Python's dwell mechanism retains only one copy of the same string.

2. When the same string is created later, the new space is not opened up, but the address of the string is given to the newly created variable.

Example

> a = '123' > b =' 123' > an is bTrue > id (a) 3136737523184 > id (b) 3136737523184 > > at this point, the study of "the principle of the resident mechanism of python strings" is over.
