Python is open source, cross-platform, interpretive, and interactive, and worth learning. Python’s design philosophy: elegant, unambiguous, simple. Advocate one way, preferably only one way to do one thing. Guis can be created with PyQt5, PySide2, wxPython, PyGObject, wxWidgets, etc. Code should be written in accordance with specifications to facilitate communication and understanding. Every language has its own unique ideas. Beginners need to change their thinking, practice and accumulate.
