Master PyQt5 part 1: Hello World and Template

[@Shannxy]

This is the calmest tutorial I've ever seen and I love it

[@MsPerestrojka]

best Introduction to PyQT5 hope it gets more viewers !

[@alandmoorecodes3585]

Thanks!

[@rebelScience]

I agree. Second to none!

[@QuirinF]

This series is priceless! Not only for PyQt but for learning Python in general. The combination of a slow pace while being so to the point provides a great speed of learning. And I love how you always do the detour of explaining all details and every line of code, but in a way that it's not getting repetitive. Legend!

[@meandyouandhimoverthere]

Great Video! Always wondered why some people used 'as' for importing and others didn't. Thank you! Will always use it now.

[@rekarpnevik]

This is the best PyQt5 tutorial series I've found. Thank you!

[@alandmoorecodes3585]

Thank you, sir!

[@theycallmemuzz7394]

this content is immaculate, keep it up. Deserves more views

[@odurolewis]

Hey Alan, I think you are a great teacher. God bless you for making understanding easier. Kudos

[@alandmoorecodes3585]

Many thanks!

[@DeePunter]

you are way better at teaching than some of my college professors

[@minhajabidin]

This is so informative and precise at the same time. Great work.

[@alandmoorecodes3585]

Glad it was helpful!

[@thingsiplay]

This is actually a really good tutorial. Subscribed. And thank you too, very well made.

[@thatguy6664]

Excellent...purchased the book

[@alandmoorecodes3585]

Thank you!

[@mimmotronics]

This is exactly what I needed, thank you! I'll be sure to check out your book.

[@rwbazillion]

This tutorial is awesome. I bought the book.

[@cristix11]

Definitely going to get the book.

[@srinivasanveeraraagavan271]

Really helpful! Thanks

[@imadetheuniverse4fun]

Can I just say.... THANK YOU for not doing * (star) imports! It drives me up the wall when tutorials especially do it. I think I'm going to have to buy your book based on that alone loool

[@alandmoorecodes3585]

Hah yes, I make a point to avoid these.

[@sabinbaral4132]

Thank you so much sir

[@Yousouf88]

you really great thanks

[@rebelScience]

I have started working on GUI front-end for my Bioinformatics software (basically a set of classes). This is just perfect. Thank you so much. Does your book cover much more then your videos?

[@alandmoorecodes3585]

Thanks! Yes, the book is much more complete.

[@jacktinney]

Hey Thank you!

When I try this under iPython/Spyder, the console hangs after I close the app window. Could you give us a version of your simplest 'hello world' that would work under iPython? I poked around on StackExchange and came up with this, but I don't understand what it is doing: import sys from PyQt5.QtWidgets import * # works for me without this check, but some people seem to need it app = QApplication.instance() # check if there is already an instance if not app: app = QApplication(sys.argv) w = QWidget(windowTitle = 'hello world') w.show() QApplication.setQuitOnLastWindowClosed(True) # this made it work for me app.exec_()

[@alandmoorecodes3585]

Spyder doesn't play nice with PyQt I'm afraid. From your code I'd guess the issue is that it already has a QApplication object in memory, but I don't know the full story. Never had problems with ipython, though, at least not on the terminal.

[@johnprice2731]

@@alandmoorecodes3585 Thanks for responding. Lately I realized that I can do GUI coding in Spyder using the menu item Run>Config per file... and marking the file so that it runs in a system terminal. Then I still have the Spyder editor and I can use the IPython terminal for testing one-liners. This is a comforting way to go for a recovering Matlab addict.

[@cesandr]

Is it worth it to read the book if I watch the whole series or has it the same contents ?

[@alandmoore4306]

The book goes into greater detail, and has a lot more content around more advanced PyQt5 things like multimedia, networking, databases, etc. Someone else will have to tell you if it's worth it, I'm slightly biased. :-)

[@cesandr]

@@alandmoore4306 Hey thanks for the reply! The networking and database part sounds pretty intresting.

[@HouseofFPS]

Anyone know why the QWidget's init method still runs even when I DIDNT use the super() function? class MainWindow(qtw.QWidget): pass app = qtw.QApplication(sys.argv) w = MainWindow(windowTitle="Hello World") w.show() sys.exit(app.exec_())

[@allenklingsporn6993]

Without getting too much in the weeds: Because your app is too simple to need indirect referencing for .__init__ arguments that don't exist. Also, for clarity, __init__ is the base python object for C++ Constructors. It isn't a Qt-specific method.
