"There are no function-level static variables in Python":https://code-maven.com/slides/python-programming/static-variable Thanks in advance. One way to achieve this is to tuck your variable away in a closure, so it will effectively be static for your purposes. Unfortunately, Python 2 does n...

Python Constants are variables with unchangeable values. Tearn different types of Python constants, variables like local, global, and static variables and how to use them.
There are very few situations where static-methods are necessary in Python, and I've seen them used many times where a separate "top-level" function would have been clearer. The following is verbatim from the documentation:: A static method does not receive an implicit first argument. To dec...
python staticmethod and classmethod Though classmethod and staticmethod are quite similar, there's a slight difference in usage for both entities: classmethod must have a reference to a class object as the first parameter, whereas staticmethod can have no parameters at all. ...
In this tutorial we will learn about Static variables and methods in python, defining static class variables and static methods along with simple code examples.

An example of static local variable in C: #include <stdio.h> void func() { static int x = 0; // x is initialized only once across three calls of func() printf("%d\n", x); // outputs the value of x x = x + 1; }
[c++] Define static const members in class C++类的静态成员 趣味Quiz this指针 静态成员函数没有 this 指针,只能访问静态成员(包括静态成员变量和静态成员函数)。 普通成员函数有 this 指针,可以访问类中的任意成员;而静态成员函数没有 this 指针。 类似于Python的Class和Object之间的关系。
