sqlalchemy, trying to make a connection to a local database

Question

I'm kinda knew so I don't know how to find solutions to this sort of errors. Was trying to make a connection to a local database.

from sqlalchemy import create_engine

rds_connection_string = "postgres:password@localhost:5432/ETL_DATABASES"
engine = create_engine(f'postgresql://{rds_connection_string}')

and got:

--------------------------------------------------------------------------- ImportError                               Traceback (most recent call last) <ipython-input-12-db09b1b74d73> in <module>

I'm in a jupyter notebook and using pg Admin 4 for the sql part
