从另一个程序在一个程序中的函数中调用全局变量

Question

I'm sure this is very simple, but I am trying to manipulate a global variable I have created in function from another script calling that function as follows:

Script 1:

def function_1():

   global myvar
   myvar = 1

Script 2:

from script1 import function_1

function_1()

myvar2 = myvar + 1
print myvar2

I don't know why that isn't working. I haven't been able to locate the exact answer I need on Stack Overflow or elsewhere. Can anyone assist?

Thanks

Global variables affect only the module in which they are defined. To access it, you need to get the module object:

#Script2

import script1

script1.function_1()
myvar2 = script1.myvar + 1
