You can set echo=True when instantiating your engine:

>>> from sqlalchemy import create_engine
>>> engine = create_engine("mysql://localhost/mydb", echo=True)

This causes all SQL statements to be logged via normal Python logging. You can easily capture these messages to a file by using the appropriate log configuration, as shown in these Python logging examples.
