My aiohttp webserver uses a global variable that changes over time:

from aiohttp import web    shared_item = 'bla'async def handle(request):if items['test'] == 'val':shared_item = 'doeda'print(shared_item)app = web.Application()
app.router.add_get('/', handle)
web.run_app(app, host='somewhere.com', port=8181)

Results in:

UnboundLocalError: local variable 'shared_item' referenced before assignment

How would I properly use a shared variable shared_item?

Push your shared variable into application's context:

async def handle(request):if items['test'] == 'val':request.app['shared_item'] = 'doeda'print(request.app['shared_item'])app = web.Application()
app['shared_item'] = 'bla'
