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

[rekarpnevik]

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

[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!

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

[DeePunter]

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

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

This tutorial is awesome. I bought the book.

[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?

[mimmotronics]

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

[imadetheuniversefun]

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

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()

# this made it work for me
app.exec_()

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

[ApplySkills]

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_())
