html - webbrowser.open() in python

Question

I have a python file html_gen.py which write a new html file index.html in the same directory, and would like to open up the index.html when the writing is finished.

So I wrote

import webbrowser
webbrowser.open("index.html");

But nothing happen after executing the .py file. If I instead put a code

webbrowser.open("http://www.google.com")

Safari will open google frontpage when executing the code.

I wonder how to open the local index.html file?

Answer 1

Try specifying the "file://" at the start of the URL. Also, use the absolute path of the file:

import webbrowser, os
webbrowser.open('file://' + os.path.realpath(filename))
