That's more to do with coding style. I abhor reflection and factories, so if I write Java I don't use them. That said, you can end up writing a RandomNumberGeneratorFactory in Python just as easily if you are trying to achieve the same scaling and re-usability requirements that the Java program is. The issue I run into in Python is that I need to call something which takes * args or * * kwargs, and the only way I know any of the arguments exist at all is because of some snippet of code on github, probably by the person who implemented the feature in the first place. Even if the argument is named I don't know if it should be a magic number which is defined in some enum-like class, a boolean, or a string to describe the name of what I want and pray that the library maintainers used the same capitalisation and localisation that I think is most logical. In fact, without looking at example code, I literally have no clue how to do anything. As such, with Python I end up doing copy-paste programming which is dependant on my internet speed and how many other people had the same problem already. With C/C++/Java I tend to do a more build-it-from-scratch style programming, driven mostly I think by the style of the documentation.
