Using webbrowser.open:

import os
import webbrowser

html = '<html> ...  generated html string ...</html>'
path = os.path.abspath('temp.html')
url = 'file://' + path

with open(path, 'w') as f:
    f.write(html)
webbrowser.open(url)

Alternative using NamedTemporaryFile (to make the file eventually deleted by OS):

import tempfile
import webbrowser

html = '<html> ...  generated html string ...</html>'

with tempfile.NamedTemporaryFile('w', delete=False, suffix='.html') as f:
    url = 'file://' + f.name
    f.write(html)
webbrowser.open(url)

(this grew enough I figured I should split it off as a separate answer:)

As @reptilicus points out, you can use the built-in http.server module as follows:
1. Create a web file directory and save your .html file in it.
2. Open a command-line window and do
```
cd /my/web/directory
python -m http.server 8000
```
3. Point your browser at http://127.0.0.1:8000
This only works for static files; it will not run your script and return the results (as Flask does).

Use Flask to turn your code into a local web application:

from flask import Flask
app = Flask(__name__)

@app.route('/')
def scrape_and_reformat():
    # call your scraping code here
    return '<html><body> ... generated html string ... </body></html>'

if __name__ == '__main__':
    app.run()

Run the script, and point your browser at http://127.0.0.1:5000/.
