Online Python Compiler

Use the Anku AI Tools online Python compiler to practice small scripts, list operations, loops, functions and interview-style problems from your browser. The page is designed for learners who need a clean editor, a stdin box for simple input, sample output, copy/download controls and plain-English notes about common Python mistakes. Python execution is routed through a sandbox provider when Piston is configured, so user code is not run inside the Next.js application process.

Python execution requires PISTON_API_URL or JUDGE0_API_URL in production.

How to use this Python compiler

  • Open the Python starter code or choose another example from the dropdown.
  • Add stdin only if the example reads from standard input.
  • Review stdout, errors, compile output or table results in the output panel.
  • Copy the code or download it as a .py file when the result looks right.

Python features

  • Stdin field for input-based exercises
  • Starter code for lists and formatted strings
  • Copy and download Python files
  • Clear stdout and stderr panels
  • Related compilers for language comparison
  • Sandbox-provider execution boundary

Common use cases

  • Practice beginner Python syntax
  • Test interview snippets
  • Debug list and loop logic
  • Share small teaching examples

Python example code

Shows list literals and the built-in sum function.

name = input().strip() or "Anku"
numbers = [2, 4, 6, 8]

print(f"Hello, {name}!")
print("Numbers:", numbers)
print("Total:", sum(numbers))

Sample output

Hello, Mira!
Numbers: [2, 4, 6, 8]
Total: 20

Common Python errors

  • IndentationError: Keep block indentation consistent, especially after if, for, while and def lines.
  • NameError: Check spelling and define variables before reading them.
  • EOFError: Add sample stdin when your code calls input().

Frequently Asked Questions

Can I run Python code online on this page?

Yes, when the configured sandbox provider is available. The page sends code to the provider through /api/code/run instead of executing Python inside the web server.

Does the Python compiler support input?

Yes. Add text to the stdin panel before pressing Run Code when your script uses input().

What Python examples should beginners try first?

Start with print statements, variables, if statements, loops, list operations and small functions before moving into files or packages.

Why does my Python code show EOFError?

EOFError usually means the script asked for input but the stdin panel was empty. Add sample input and run again.

Can I download the Python code?

Yes. Use the download button to save the editor content as a .py file.
