Unable to use random.choice(list) in async method

[spacedog]

I need to pull a random proxy from a list in an async method but the code exits the method as soon as it hits the line of code:

proxy = random.choice(proxy_list)

Here's the full method and the next line (the "print" line) never executes.

async def download_site(session, url):
    proxy_list = [
    (754, '38.39.205.220:80'),
    (681, '38.39.204.100:80'),
    (682, '38.39.204.101:80'),
    (678, '38.39.204.94:80')
    ]
    proxy = random.choice(proxy_list)
    print(proxy[1])
    async with session.get(url, proxy="http://" + proxy[1]) as response:
        print("Read {0} from {1}".format(response.content_length, url))

Can someone please share a work-around or a fix for this?
Thanks.
