out_file = open("/var/www/index.html", "wt")
print ("Writing file, Date and time = ", str(now))
out_file.write("<p>This is Eric Pierce's Raspberry Pi Webserver.</p>\n")
out_file.write("<p>Date and time = " + str(now) + "</p>\n")
If that is saved in your default folder with the name "webtest.py" you can run it as so (it needs root privs to do this, that is what the sudo prefix does):
$ sudo python3 webtest.py
Then if you connect to the raspberry pi with a browser from another computer, you see the page with the time. If you hit the browser refresh button evety 5 seconds, you will see the time, date, etc.
Only a few more lines of code to read digital events in your house from switches, and a bit more to read analog values. Open up a port in your firewall, and you can access it from the world.
With a bit more work, you could put buttons on the page to control things!
