Query my database on AWS over an SSH tunnel with Pandas - mysql

Question

I am trying to query to my database running on AWS over an SSH tunnel with Pandas. But I fail login. Also there is one key that I use to connect on SQL client (Sequel Pro) that I don't know how to use in my python code.
This is the key: heroes-us-west-1-master.cheme3bzdejb.us-west-1.rds.amazonaws.com
This is my code:
with SSHTunnelForwarder(
(host, 22),
ssh_username=ssh_username,
ssh_private_key=ssh_private_key,
remote_bind_address=(localhost, 3306)
) as server:
conn = db.connect(host=localhost,
port=server.local_bind_port,
user=user,
passwd=password,
db=database)
return pd.read_sql_query(q, conn)
df = query("SELECT stores.name, stores.address\
FROM stores;")
This is the error message:
Traceback (most recent call last):
File "connection.py", line 32, in <module>
FROM stores;")
File "connection.py", line 22, in query
remote_bind_address=(localhost, 3306)
