How to delete a table in SQLAlchemy?

Question

I want to delete a table using SQLAlchemy.

Since I am testing over and over again, I want to delete the table my_users so that I can start from scratch

Below is example code you can execute in iPython to test the creation and deletion of a table on Postgres

from sqlalchemy import * # imports all needed modules from sqlalchemy

engine = create_engine('postgresql://python:python@127.0.0.1/production') # connection properties stored

metadata = MetaData() # stores the 'production' database's metadata

users = Table('users', metadata,
Column('user_id', Integer),
Column('first_name', String(150)),
Column('last_name', String(150)),
Column('email', String(255)),
schema='python') # defines the 'users' table structure in the 'python' schema of our connection to the 'production' db

users.create(engine) # creates the users table

users.drop(engine) # drops the users table
