Name Error: name 'User' is not defined. I cannot add my name to the userbase because of this error.

I'm currently working on the SQLAlchemy course and my file won't update with my name because of this name error, however I copied what Megan did during her demonstration and I'm not sure what could have been wrong. It's supposed to follow the format of the repr(self) function in the models.py, so I'm not sure what went wrong for me. I'm using the Treehouse console. This is the line of code that got the error: abi_user = User(name='Abigail', fullname='Abigail Solomon', nickname='Abi').

Here's the full code:

from sqlalchemy import create_engine, Column, Integer, String from sqlalchemy.ext.declarative import declarative_base from sqlalchemy.orm import sessionmaker

engine = create_engine('sqlite:///users.db', echo=True) Session = sessionmaker(bind=engine) session = Session() Base = declarative_base()

class User(Base): tablename = 'users'

id = Column(Integer, primary_key = True) name = Column(String) fullname = Column(String) nickname = Column(String)

def repr(self): return f'<User(name={self.name}, fullname={self.fullname}, nickname={self.nickname})>'

if name == 'main': Base.metadata.create_all(engine)

abi_user = User(name='Abigail', fullname='Abigail Solomon', nickname='Abi')
print(abi_user.name)
print(abi_user.id)
session.add(abi_user)
print(session.new)
