Issues with changing variable using checkbox

问题

I'm quite new to Python and was having some confusing issues. I have two scripts main.py and second.py. I have a base url that needs to be changed in the second.py see bellow example

def getVarientStock(self, sku,base="http://www.baseurl.com"):
    urlVariantStock = base + '/Product-GetVariants?pid=' + sku
    r = requests.get(urlVariantStock, headers=self.headers)
    try:
        versions = json.loads(r.text)['variations']['variants']
    except:
        if r.status_code == 404:
            return {'error' : '"' + self.sku + '" is an invalid SKU!'}
        else:
            return {'error' : 'There was an error checking Stock, make sure the SKU is correct and try again.'}
        return

Now in main.py I am trying to figure out how I can have multiple different checkboxes to assign different base url's. I beleive the issue I am having is because it is a local variable?? second.py is imported into main.py.

This is the checkbox

is_checked = IntVar()
        self.aucheck = Checkbutton(self.master, text='AU', onvalue=1, offvalue=0, variable=is_checked)
        self.aucheck.pack(in_=top, side=LEFT)

And this is the funciton that I'm trying to figure out

def callcheckbox(self,):  
    if(is_checked.get()):
       getVarientStock.base =("XX","http://www.adidas.com.au/on/demandware.store/Sites-adidas-AU-Site/en_AU")

Really appreciate the assistance!! Sorry if this is a silly question Im still learning
