About using and updating Python global variables

Asked 2 years ago, Updated 2 years ago, 133 views

from settiing import *

from boy import *


def start():

     value = web() // Import data from the web (value=[4,5,6])

     gosetting(value)

     goBoy()
a = 1

b = 2

c  = 3

def goSetting(value):

     global a

     global b

     global c

  if value:

      a = value[0]

      b = value[1]

      c = value[2]


  else:

     pass
from setting import *

def goBoy():

    print("a: ", a)

Let me ask you a question.

The goBoy() value of the main.py file is I want to get the a:4 value, but a:1 comes out.

In the end, I want to use the a, a, b, and c values in other modules like global variables, but this doesn't work!

How can I use data that I received on the web initially as a global variable?

If it were me, setting.I'll make a class called setting by modifying the py a little bit.

class Setting:
    def __init__(self, value):
        if len(value) == 3:
            self.a = value[0]
            self.b = value[1]
            self.c = value[2]
    def goBoy():
        print("a: ", self.a)a)
def start():
    value = web()
    s = Setting(value)
    s.goBoy()
