'How To Use Url Schemes With Search Engines In PyQt5
So, I want to be able to also search things up with a search engine but also being able to put in URLs in the url bar, so like a modern web browser like Google Chrome or Firefox. This has to do with Schemes I'm pretty sure and the Scheme part of my script. I tried to put a base url like "https://www.google.com/search?q=" or "https://duckduckgo.com/?q=" but sadly that just errored out, then I tried to put the scheme as the regular https but then I put and else statement which stated that if there is no .com or .ca or www or https:// in the url bar when searched then it will search it up on the search engine, otherwise just put it as a url; that also errored out. So, how could I approach this? Also, any suggestions to how to make this more efficient? Thank you in advance! :D

Solution 1:[1]
You can use QUrl.FromUserInput:
def navigate_to_url(self):
#Convert it to QUrl object.
q = QUrl.FromUserInput(self.urlbar.text())
if qurl.isValid():
self.browser.load(qurl)
else:
qurl = QUrl("https://duckduckgo.com/?q=%s" % q)
self.browser.load(qurl)
But this doesn't work if the URL contain only one word.
