title: How to get table names and their data types from session/engine/meta in sqlalchemy?
body: <p>Suppose I have a Model:</p>
  <pre><code>class User(Base):
      __tablename__ = 'users'
      id = Column(Integer, Sequence('user_id_seq'), primary_key=True)
      name = Column(String(50))
      fullname = Column(String(50))
      nickname = Column(String(50))
  
  </code></pre>
  <p>Now in code, I want all the data types of the User class, what is the best possible way of doing that?</p>
