Hello, Python 👋
Python is a language for telling computers what to do, written in a way that looks a lot like English. Every program you will ever write is built from small instructions like the one below.
Your first instruction
print("Hello, world!")print() is a function: a named action. Whatever you put inside the brackets gets shown on the screen. The text is wrapped in quotes so Python knows it is text rather than code.
Comments
# This is a comment. Python ignores it.
print("Comments help humans, not computers")💡 You can print several things at once:
print("Age:", 30) shows Age: 30.Why Python?
It runs websites (Instagram, Reddit), powers data science and AI, automates boring office jobs and is the most requested language in UK job ads for entry level developers.
Your challenge
Print exactly two lines: Hello, Pythonaut! and then Ready for launch.
