PYTHON IS A SUPERSTAR
The language you will learn does big things.
PyBot speaks Python. So do many scientists and app makers.
A photo of a black hole
In 2019, scientists showed the first photo of a black hole. Python helped them put the picture together.
Apps millions of people use
Big apps, like Instagram, use lots of Python to keep running.
Scientists and space agencies
Scientists at places like NASA use Python to study planets, weather and animals.
Robots and Minecraft
Kids code small robots, tiny computers and Minecraft worlds with Python.
YOUR FIRST CODE
Say hello like a real programmer.
Press Run Python. The computer does exactly what the code says.
OUTPUT
PyBot's hint
Ready. Press Run Python.
