You can use the length() function in SQLAlchemy to find attributes based on their length. Here's an example:
from sqlalchemy import length
# Assume we have a User model with a 'name' string attribute
# that we want to find based on its length
users = session.query(User).filter(length(User.name) > 10).all()
# This will return a list of all the user objects whose name attribute
# is longer than 10 characters
You can also use func.length() instead of just length() if you want to be more explicit about calling a function.
