Python has become the default language for data work, and Andreas Kretz built this course to teach it specifically through a data engineering lens — useful whether you're starting out or already experienced and filling gaps.

What you'll practice

  • Advanced Python features and transforming data with pandas
  • Integrating with APIs and working with PostgreSQL, dates, and JSON
  • Object-oriented programming: classes, objects, and data validation
  • Writing unit tests and handling exceptions properly
  • Working with modules and using NumPy for numerical computation

Across 19 lessons and a companion GitHub repo, the focus stays on building reliable, efficient data pipelines rather than general-purpose Python — skills meant to translate directly into real data engineering work.

Who teaches Python for Data Engineers? Andreas Kretz

Andreas Kretz thumbnail

Andreas Kretz is a German data engineer and one of the most widely followed independent voices on data engineering as a career discipline. He runs the Plumbers of Data Science brand and has been publishing tutorial material continuously since the field consolidated around the modern lake-house stack (Spark, Kafka, Snowflake, Databricks, Airflow).

His CourseFlix listing is the largest single-author catalog under this source — over thirty courses spanning data-pipeline construction, streaming architectures, the cloud-native data stack on AWS / Azure / GCP, the Python and Scala tooling that dominates the field, and the soft-skills / career side of breaking into data engineering. Material is paid and aimed at engineers transitioning into data work or already-working data engineers picking up specific tools.
