Code Py

Learn Python in your browser

Offline ready after download • Free • No account needed

Write real programs — not fill-in-the-blanks. Press Run and Python actually executes your code.

You type the whole program. It really runs in your browser, and automatic tests grade it with instant pass/fail and feedback.

Lessons are built on real-world cases — notifications, billing, inventory, payments. Read, write, run: that is all it takes.

customer = "Ana" # your first automatic notification print("Welcome to the system,", customer)

Program output

Welcome to the system, Ana
