Accessing Trino Via Python

I'm trying to access trino via python and I keep getting the error below. This is to access the trino interface and retrieve data from oracle. Please advise on how this can be resolved.

RunTimeError in Twint : This event loop is already running

I use a jupyter notebook and run twint.
Code
c = twint.Config()
c.Username = 'twitter'
c.Limit = 20
twint.run.Followers(c)
The above commands produce a runtime error relating to (I believe) the code attempting to create 2 asynchronous event loops.
Traceback as follows:

I have found a solution for Jupyter notebooks
using the nest_async
Simply do
pip install nest_asyncio
And add these lines.
import nest_asyncio
nest_asyncio.apply()

Google AdManager getCurrentNetwork() error

I have set up ad manager credentials. I'm trying to access the Admanager API, im getting the following error.
from googleads import ad_manager
client = ad_manager.AdManagerClient.LoadFromStorage()
network_service = client.GetService('NetworkService', version='v201902')
current_network = network_service.getCurrentNetwork()

You are probably missing permissions with your configured service account. Make sure the account has access to ad-manager and scopes are configured properly.

I suggest to do it this way:
class Adx:
def __init__(self):
self.GOOGLEADS_YAML = 'googleads.yaml'
self.GOOGLEADS_VERSION = 'v202111'
self.google_keys = self.GOOGLEADS_YAML
def activate(self):
ad_manager_client = ad_manager.AdManagerClient.LoadFromStorage(self.google_keys)

Catching HTTPerror in python3 from stravalib function

My code (for the relevant part) is as follows
myactivities = []
from urllib.error import HTTPError
for activity in client.get_activities(after = activities_from, before=activities_to):
print(activity)
print(activity.id, activity.start_date)
try:
temp = client.get_activity_streams(activity.id, types=types)
except urllib.error.HTTPError:
print("HTTPError")
myactivities.append(temp)
The error print I get is this:

HTTPError: 404 Client Error: Not Found [Record Not Found: []]
During handling of the above exception, another exception occurred:
NameError Traceback (most recent call last)
<ipython-input-29-fc30cef1e4f3> in <module>()

NameError: name 'urllib' is not defined
How can I catch that HTTPError succesfully? I tried all the suggestions in catch specific HTTP error in python but none helped.

Try
myactivities = []
from urllib.error import HTTPError
for activity in client.get_activities(after = activities_from, before=activities_to):
print(activity)
print(activity.id, activity.start_date)
try:
temp = client.get_activity_streams(activity.id, types=types)
except HTTPError:
print("HTTPError")
myactivities.append(temp)
You already imported HTTPError, you have to use directly.
Your code shows error.

11 print("HTTPError")
12 myactivities.append(temp)
NameError: name 'urllib' is not defined
Which gives error because urllib is not accessible. You imported HTTPError from that.
