将全局变量传递给Python中的另一个文件？

Question

我有

# file1.py
global a, b, c, d, e, f, g

def useful1():
   # a lot of things that uses a, b, c, d, e, f, g

def useful2():
   useful1()
   # a lot of things that uses a, b, c, d, e, f, g

def bonjour():
   # a lot of things that uses a, b, c, d, e, f, g
   useful2()

和

# main.py   (main file)
import file1

# here I would like to set the value of a, b, c, d, e, f, g  of file1 !

bonjour()

如何处理所有这些全局变量？

PS:我不想a, b, c, d, e, f, g为所有功能添加,这将是非常多余的:

def useful1(a, b, c, d, e, f, g):
...
def useful2(a, b, c, d, e, f, g):
...
def bonjour(a, b, c, d, e, f, g):
...

Answer 1

你不需要传递它们.如果你已经import file1在main.py的顶部完成了,你可以直接引用file1.a等.

然而,拥有这么多全局变量闻起来非常糟糕.您可能应该使用类重构.
