When you run this command, Python will start a web server on port 8000 and serve the files in the current directory as static web pages. \newline % Row Count 16 (+ 3)

Open a terminal or command prompt in the directory where you want to serve files. \newline % Row Count 19 (+ 2)
Run the command "python -m SimpleHTTPServer" or "python2 -m SimpleHTTPServer" (depending on your Python version). \newline % Row Count 22 (+ 3)

Open a web browser and navigate to "http://localhost:8000" to see the files being served. \newline % Row Count 26 (+ 2)
Note that this command is intended for testing and development purposes only and should not be used in production environments. Also, if you're using Python 3, the command has been changed to "python -m http.server" or "python3 -m http.server".% Row Count 31 (+ 5)
