With YaliCode, you get:

  • Python 3.11 ready to go
  • Instant execution — results in under 2 seconds
  • No installation required
  • 23 languages including Python, JavaScript, Go, Rust, and more
  • AI-powered code completion and error explanation
  • Getting Started

    1. Open [yalicode.dev/editor](https://yalicode.dev/editor)

    2. Select the Python template

    3. Write your code

    4. Press Ctrl+Enter to run

    ```python

    # Your first Python program on YaliCode

    name = input("What's your name? ")

    print(f"Hello, {name}! Welcome to YaliCode.")

    ```
