- Create a variable named impressions.
- Use the integer value 125000.
Expected result
- impressions equals 125000.
Python example
Practice editor
Type Python here. Nothing is executed.
Drafts are stored in this browser for this example only. No Python is executed.
Notes
- Python uses a single equals sign to assign a value.
- Variable names should be readable and descriptive.

Python practice guide
Practice Python syntax for AdTech debugging
Python Syntax Lab helps you build confidence with common Python patterns used around ad logs, bid requests, VAST XML, CSV exports, reporting cleanup, and lightweight troubleshooting scripts.
What you can practice
Work through variables, strings, lists, dictionaries, conditionals, loops, functions, JSON parsing, XML parsing, CSV handling, error handling, fill-in-the-blank drills, and ad-tech metrics such as CPM and fill rate.
Why it does not execute code
This version is intentionally practice-only. You get highlighting, examples, drafts, completion progress, and optional local feedback without sending Python to a backend or running untrusted code in the browser.
How to build fluency
Use Write code for memory practice, then switch to Fill blanks when you want to practice specific intermediate and advanced syntax pieces inside larger snippets.
FAQ
Does Python Syntax Lab run Python?
No. It is a syntax practice environment with highlighting, local drafts, completion progress, fill-in-the-blank drills, and optional local feedback. Nothing is executed or sent to a Python runtime.
Are the examples beginner friendly?
Yes. The library includes beginner examples and gradually moves into more realistic intermediate and advanced AdTech data patterns.
Why include VAST and OpenRTB examples?
AdTech troubleshooting often involves JSON bid requests, XML ad responses, CSV reports, and messy logs. The examples mirror those everyday formats.
Are drafts private?
Drafts, blank answers, and completion progress are saved locally in your browser. The Python lab does not require an account and does not submit practice code to a backend.
