Correct so I have changed to this: 
def get\_exchange\_accounts(connection):
 try:
 cursor = connection.cursor()
 query = """
 SELECT DISTINCT exaccount\_id FROM account;
 """
 cursor.execute(query)
 exaccounts = cursor.fetchall()
 cursor.close()
 return exaccounts
 except (Exception, psycopg2.Error) as error:
 print("Error while fetching data from PostgreSQL", error)
 return None

all\_accounts = get\_exchange\_accounts(connection)
print("All Accounts including Wallet, Bank, and Exchanges: ", all\_accounts)
  Great, it looks like you've made some progress on your function to retrieve exchange accounts from a PostgreSQL database! Here are some additional suggestions to improve your code:

1. Use a more descriptive name for your function: `get_exchange_accounts` is a bit vague, and it's not immediately clear what the function does. Consider renaming it to something like `get_exchange_account_information` or `get_exchange_accounts_list`.
2. Use a consistent indentation style: In your code, you're using both spaces and tabs for indentation. It's better to use a consistent indentation style throughout your code, so I recommend using spaces exclusively.
3. Use a more descriptive name for the `query` variable: The `query` variable is a bit vague, and it's not immediately clear what it represents. Consider renaming it to something like `exchange_account_query`.
4. Consider using a context manager for the database connection: Instead of opening and closing the database connection manually, consider using a context manager like `psycopg2.extras.ConnectionContext` to manage the connection for you. This can simplify your code and make it easier to use.
5. Use a more robust error handling mechanism: Your code catches only the `Exception` and `psycopg2.Error` exceptions, but it doesn't
All Accounts including Wallet, Bank, and Exchanges: [{'exaccount_id': '00000001'}, {'exaccount_id': '00000002'}]
