Coding A Simple Web Browser in Python

[@dany_fg]

this is great for django/flask/fastapi based apps, as you can create a web window for the server without the user even realizing

[@addledanorak8297]

Another great use case for this (This is what i do in my projects sometimes): You can use this for creating awesome looking UIs. Just write a simple flask app and run the two things simultaneously so that now you can use HTML/CSS for UI instead of Qt5. I personally love using HTML/CSS so i use this trick for creating complex UIs in projects. Without the buttons on the top (go back, reload etc), it just looks like a window of some usual software.

[@robinferizi9073]

But how do you get your flask app on the window

[@addledanorak8297]

7:16 Use the setUrl function and pass in the localhost url your flask app is running on

[@robinferizi9073]

@@addledanorak8297 but how would you show other webpages? And how would you keep the url bar and whatnot there

[@MrinmoyHaloi]

@@robinferizi9073 you can do that with html and js

[@addledanorak8297]

@Robin Ferizi what I meant was to use the browser as a window that can show your flask project so that u can use html and css for ui and it looks like a professional software. That's all

[@dicember92]

Man, I need to say thanks! I crashed my head for an entire day trying to make a simple UI to stream a local server network content for a local community. I tried with socket, but I couldn't resolve my problem. Watching your video I understood that I could make a non navigable-browser with PyQt5. So a huge thanks!!

This is not "coding web browser", it's just "using web browser" in your application.

[@whereisyourhijab]

Browsers basically use search engines to search and he is doing that. Making a browser doesn't mean you have to code the search engine yourself too

[@cipherxen2]

​@@whereisyourhijabwhat search engine has to do with it? Do you even understand my comment.

[@Logan_Wolf_Online]

@@cipherxen2 You are using lines of code to set up an interface to interact with websites. Ergo you are coding a web browser. You can use C in Windows to create a Desktop app that does the same thing, and it is still coding an GUI program that lets you browse the web, a "web browser". What, do you want him to write it from Assembly instead?

[@cipherxen2]

​@@Logan_Wolf_Onlineso by your logic, if I write a program import MyWebBrowser MyWebBrowser() Did I create a web browser? Or just used an existing one?

[@sabungee4442]

9:08 what is exit code -1?

[@Epsultamma]

The exit code is just a Boolean telling you if something went wrong. 1 means something did go wrong, and thus equates to true, and 0 means everything went as planned, and thus equates to false. If you are having issues with the project opening when you added the back and forward buttons implemented as it is in the video, try typing "lambda: " before the self.browser forward and back functions. It works for me.

After seeing your videos (which ones are really good), I was wondering if it is possible to create a KZbin clone or Twitch clone with Python and Flask... I was trying to search the way to connect the OBS for live streaming to an specific app created on Python but no clue found on internet... maybe you know or you can help me with that question. Thanks!!

Am I able to add extensions and plugins and stuff?

[@MrinmoyHaloi]

no you can't. although it uses code from chromium (chrome is based on chromium) but its modified to work better with qt. all of the google services are striped out. so i think you can't install extensions.

[@kaanakdik9455]

I solved the problem. It is necessary to use PySide2 instead of PyQt5. There is a licensing difference between them. The codes are exactly the same. Just use PySide2 instead of PyQt5 during import. But still i wonder that why PyQt5 don't show the web page. What does that have to do with PyQt5 licensing?

Great video-tutorials, amigo. You're good! And I have a question hoping you can answer: I have been trying to create an app where I can open three websites in three different QTabs. Using PyQt5 or PyQt6. But my sites have chats, and the chat doesn't load along with the website unless I use pywebview. So my question is: how can I add tabs to a window using pywebview and display a site in them, so I can select from a dropdown the site that I want to open (within the same window, not multiple windows)?

I am trying to create a web browser using your video. It worked good, I can connect to my Disney+ account but the issue comes when I try to play a video. It's seems that Dineyplus blocked access if it doesn't recognise the browser ? Or a library PIP is missing ? Could you help please ?

[@navinross3357]

It's possible that Disney+ has implemented some form of browser detection to block access to their videos if the browser is not recognized. This is a common technique used by streaming services to prevent piracy and unauthorized access. To work around this issue, you can try spoofing your browser's user agent to make it appear as a different browser that Disney+ recognizes. You can do this by adding an HTTP header to your requests with the user agent string of a known browser.
