Python Tutorial
Learn Python, the beginner-friendly language used for automation, web development, data science and AI.
Python is a high-level, interpreted, dynamically typed, general-purpose language created by Guido van Rossum and first released in 1991. Its clean, readable syntax uses indentation instead of braces to mark blocks of code.
Your First Python Program
print("Hello, Python!")Hello, Python!
That's the whole program. There's no class, no main and no semicolon.
