How to use GC algorithm in Python

In this article Xiaobian for you to introduce in detail "how to use the GC algorithm in Python", the content is detailed, the steps are clear, and the details are handled properly. I hope that this article "how to use the GC algorithm in Python" can help you solve your doubts.

Concept

1. It is divided into three points: reference marking-clearing / generational recycling.

At the core of each object in Python is a structure PyObject with a reference counter.

Typedef struct_object {int ob_refcnt; struct_typeobject * ob_type;} PyObject

2. Advantages

Simple real-time (once zero, no more BB with you, get rid of)

3. Shortcomings

Strong maintenance ability (simple real-time, but takes up some additional resources, although the logic is simple, but it is very troublesome. Just like you eat strawberries, wash your hands once, not finish.

What are the data types of python? the data types of python:

1. Numeric types, including int (integer), long (long integer), and float (floating point).

two。 String, which is of type str and type unicode, respectively.

3. Boolean, Python Boolean is also used for logical operations and has two values: True (true) and False (false).

4. List, the list is the most frequently used data type in Python, and any data type can be placed in the collection.

5. Tuples are identified by "()", and internal elements are separated by commas. 6. A dictionary is a collection of key-value pairs.

7. A collection is an unordered, non-repeating combination of data.
