m = re.search('a class="profileLink" href="([^"]+)"', html)
href = m.group(1) #will be https://www.facebook.com/$FB_USER_NAME on 201705.24
username = href.split('/')[-1]

While the 2.0 SDK will not provide the username field any longer, it is quite easily scraped if you have the user id number (which you will likely be using to access the graph anyway).

The url facebook.com/<user id> will redirect to facebook.com/<username>, which can then be extracted however you like.
