Python Tutorial — Learn Python Step by Step

Run Python Online

You can write and execute Python code directly in your browser — no installation, no setup, no downloads. Our free online Python compiler gives you instant feedback, making it perfect for learning, experimenting, and testing code snippets.

How to Use the Online Python Editor

1. Open the editor: Go to our Python Compiler page.
2. Write your code: Type or paste Python code in the editor panel.
3. Click Run: Your code is executed on a Python 3 server and output appears in the console panel.
4. Provide input: If your program uses input(), add test data in the stdin/input box.
5. Share: Click Share to get a URL with your code pre-loaded for others to run.

Try These Examples

# Your first Python program
print("Hello, World!")

# Variables and math
x = 10
y = 3
print(f"{x} + {y} = {x + y}")
print(f"{x} * {y} = {x * y}")

Expected output:

Hello, World!
10 + 3 = 13
10 * 3 = 30

# Reading user input
name = input("What is your name? ")
age = int(input("How old are you? "))
print(f"Hello {name}! You will be {age + 10} in 10 years.")

Add Alice and 25 to the input box (one per line) before running.
