Why this code doesn't work? I have a global variable which I need to assign value to it by getting data from json:

regional = ''

def getData(manager):
    with open("temp/" manager ".json", 'r') as j:
        json_object = json.loads(j.read())
        for result in json_object['results']:
            username = (result['username'])
            if level == 1:
                regional = username
                print(username)

the print at the end works and shows the username but it doesn't assign it to regional which is the global variable. It's empty. In the VSCODE, it's showing as not accessible.

You have to declare the variable as global to be able to modify it:

regional = ''

def getData(manager):
    global regional  # <- HERE
    with open("temp/" manager ".json", 'r') as j:
        json_object = json.loads(j.read())
        for result in json_object['results']:
            username = (result['username'])
            if level == 1:
                regional = username
                print(username)

Please use global keyword. I recommand you to reference this page : https://www.geeksforgeeks.org/global-keyword-in-python/
