How can Python scripts be executed within a database migration process?

There are several ways to run Python scripts during database migrations:

1. Calling scripts from the migration tool

   • Many migration tools (e.g., Alembic, Flyway) allow executing arbitrary scripts or commands during migration.

2. Using system calls from Python

   • If migrations are written in Python, you can run other scripts via subprocess:

import subprocess
subprocess.run(["python", "script.py"] , check=True)

3. Integration with ORM or migration libraries

   • Embedding script logic directly into migration files.

4. Using shell scripts

   • Wrapping migrations and Python script execution in a shell script that sequentially performs the necessary steps.

The choice of method depends on the migration tool used and the project architecture.
