You often have the case that a base class can implement a lot of functionality based on a few methods defined by derived classes. An example is a mapping class (with methods such as keys, values, items, iteration, subscription, ...). All those methods can be implemented generically based on "__len__", "__iter__", "__getitem__" and "__getitem__". In those cases, you can decorate the base methods with `abstractmethod`. Formerly, you had `raise NotImplementedError` in the body of those methods. If a derived class forgot to implement a required method, the exception was raised as soon as the method was called. With `abstractmethod` you see the problem earlier. -- https://mail.python.org/mailman/listinfo/python-list
Regarding the issue I had faced
Hi I would to like to say that Python is a very good language with a vast area of application and an easy way to start for the beginner. I am also a beginner and I am very much comfortable with syntax of Python. Now coming to my problem. Say for example if I have created a n HTML file and want to edit it in Brackets , I will right on the file and select the option “ Edit with Bracket” . We also have a similar thing in IDLE too , when we right click on .py file we get the option “ Edit with IDLE” comes but I don’t get that option on right clicking .py file . One more hint regarding the problem I mentioned is that when I select the repair option in Python Setup window a dialog box appears stating “ Ensure you have access to “ . I am using Windows 10 Home 64-bit (Specification of my laptop) , I hope it will help. Please contact me on the same email id to help me resolve the issue . I would be very much thankful to developer team for the help from your side. Sent from Mail for Windows 10 -- https://mail.python.org/mailman/listinfo/python-list

Qt does support mobile and touch oriented user interfaces. Also, it does support GUI programs on microcontrollers now on bare-metal. Desktop development has long moved out of the focus of the Qt company. (This shift dates back to the time when Nokia was the owner.) Just have a look at their start page and you know the focus. Qt company is living from expensive industry licenses. Providing frees solutions to the open source community is not the core business. Qt still supports traditional desktop development in form of Qt Widgets, but there's pressure to move to QML. This is more comparable to the HTML/CSS/Javascript approach. Personally I would not want to go that way for desktop applications. The traditional single-language approach with API and debugger seems much more straightforward and time-saving. For many types of desktop applications I would just recommend wxPython, together with wxGlade as a GUI builder. This will provide a quick start and high productivity for many tasks. That's another point: Qt Designer is recognized as one of the most advanced GUI builders, but when you actually want to use it with Python it does not really help you much. Using it is too complicated for the beginner or casual user and for the advanced user it's easier to avoid it completely. Regards Dietmar -- https://mail.python.org/mailman/listinfo/python-list
