python - 在Django中定义全局对象

Answer 1

That is to say, your data life cycle is the python running cycle.
In this case, you only need to separate one module (single file or multiple files).
For example, calculator.py calculator.py
内容为：

# coding=utf-8

__all__ = ["cal1"]

_g = None

class _Calculate(object):
    def __init__(self): pass

    def cal1(self):
        # do some calculate
        return

if _g is None:
    _g = _Calculate()

def cal1():
    return _g.cal1()

使用方式 import calculator 或 from calculator import *The content is:

Usage method import calculator or from calculator import * can be used🎜Not limited to Django🎜
