Adding CSS to my html blows up my python code

I'm trying to add CSS to the HTML that my python code generates. This line causes an error when I post the HTML:

html += '<link rel=\'stylesheet\' href=\'{{ url_for(\'static\', filename=\'css/main.css\') }}\'>'

I also tried putting the quotes on the outside, I get the same error:

html += "<link rel=\'stylesheet\' href=\'{{ url_for(\'static\', filename=\'css/main.css\') }}\'>"

The error I'm getting is:

requests.exceptions.HTTPError: 400 Client Error: Bad Request for url:

if I remove that one line I can PUT to the web page.

This is the code that writes the HTML to the page:

def write_data_to_confluence(auth, html, pageid, title = None):
    info = get_page_info(auth, pageid)
    ver = int(info['version']['number']) + 1
    ancestors = get_page_ancestors(auth, pageid)
    anc = ancestors[-1]
    del anc['_links']
    del anc['_expandable']
    del anc['extensions']
    if title is not None:
        info['title'] = title
    data = {
        'id' : str(pageid),
        'type' : 'page',
        'title' : info['title'],
        'version' : {'number' : ver},
        'ancestors' : [anc],
        'body'  : {
            'storage' :
            {
                'representation' : 'storage',
                'value' : str(html)
            }
        }
    }
    data = json.dumps(data)
    url = '{base}/{pageid}'.format(base = BASE_URL, pageid = pageid)
    r = requests.put(
        url,
        data = data,
        auth = auth,
        headers = { 'Content-Type' : 'application/json' }
    )
    r.raise_for_status()
    print("Wrote '%s' version %d" % (info['title'], ver))
    print("URL: %s%d" % (VIEW_URL, pageid))

I think I am quoting it wrong. I tried a couple different ways, but have yet to get it right. How can I quote this correctly?

Try this approach,

html += "<link rel=\"stylesheet\" href=\"{{ url_for('static', filename='css/main.css') }}\">"

Escaping single quotes is not required as the string is enclosed in double quotes. The attribute values are enclosed in double quotes.

or, using triple quotes

html += """<link rel="stylesheet" href="{{ url_for('static', filename='css/main.css') }}">"""

If you want to use string interpolation ({{ url_for...) then you need to use f-strings: f'interpolation: {{url_for(whatever)}}'

Also you can use double-quoted strings and not bother escaping every single quote: print("Single 'quotes' are fine here")

In more complex cases you can use multiline stings, they can contain newlines and other quote markers inside them, ''' this 'is' "ok" '''. There are '''string''' and """string""" versions, functionally the same.
