Accessing country_code of a tweet using tweepy raises "AttributeError from None"

I am trying to write code to print the country code of all tweets that match a search query. I have tried to follow tweepy examples as well as twitter's documentation and examples on the internet, but I have not been able to find the way to do it. I have academic research access to the API, and this is my code (the query is a toy example):

import tweepy


bt = "..."

client = tweepy.Client(bearer_token=bt)

query = 'hello has:geo -is:retweet'

response = client.search_all_tweets(query=query, tweet_fields=['geo'], place_fields=['country_code'],
                                  expansions=['geo.place_id'], max_results=10)

tweets = response.data
includes = response.includes
places = includes["places"]
places = {p["id"]: p for p in places}

for tweet in tweets:
    print(tweet.id)
    print(tweet.text)
    print(" country:    ", tweet.country_code)

I get the following error:

line 67, in <module>
    print(" country:    ", tweet.country_code)
  File "mypath", line 35, in __getattr__
    raise AttributeError from None
AttributeError

I have tried adding this if statement I found in another question:

if tweet.place is not None:
    print(" country:    ",tweet.country_code)
else:
    print("Place not found")

But it raises the same error, but this time on the if statement line. I have tried printing the tweet.geo field but all it does is print the place id, which is not what I want.

I have seen many responses about how to filter by country. But this is for a linguistics research on the use of specifc structures around the world, so I need to get all of its uses and information on the country where the tweet was posted from.

How can I get the country code?

I manage to find a solution tanks to @mkrieger1 's help.

response = client.search_all_tweets(query=query, tweet_fields=['geo'],
                                    place_fields=['country_code'],
                                    expansions=['geo.place_id'], max_results=10)

tweets = response.data
includes = response.includes
places = includes["places"]
places = {p["id"]: p for p in places}

for tweet in tweets:
    try:
        print(tweet.text, "     ", places[tweet.geo["place_id"]]["country_code"], "\n")
    except:
        print("Country not found")

This solution does still yield tweets for which the country information is not set. The filter is applied in the for loop.
