How Python Data Engineers Use Pony ORM

Python data engineers use Pony ORM when they want database queries that read like Python rather than SQL. Queries like `select(u for u in User if u.age > 25)` are translated to optimized SQL at runtime. This makes Pony ORM a good fit for analytics scripts and reporting tools where code readability is a priority.
