Run Python in your browser

Real Python 3, compiled to WebAssembly and running inside this page. The first run downloads the interpreter once – after that it starts instantly and even works without internet. Nothing you type leaves your browser.

What works and what does not

      

        

          
Works

          
    
            
  • All of core Python 3 – data types, loops, functions, classes, comprehensions
    • 
            
  • Standard library: json, re, random, datetime, collections, csv, math
    • 
            
  • Writing and reading files in the browser’s temporary filesystem
    • 
            
  • Exceptions, assertions and your own test helpers
    • 
          

        

        

          
Does not work here

          
    
            
  • Selenium / Playwright – they need a real browser driver on your machine
    • 
            
  • requests and network calls – the browser blocks them for security
    • 
            
  • pip install of packages that need compiling
    • 
            
  • input() – there is no console to type into
    • 
          

          
For automation practice, install Python on your machine and use our framework downloads.
