- Python:
Use the command python -m http.server (Python 3) or python -m
SimpleHTTPServer (Python 2) in the terminal.
- Access
Your HTML File in the Browser:
- Open
your browser and type http://localhost/<filename>.html in the
address bar.
- Replace
<filename> with the name of your HTML file.
Running on localhost mimics a real server environment,
making it an excellent choice for testing dynamic or multi-page applications.
Conclusion
