Is there a lightweight splash screen for python3?

Question

Python

When PyQt is launched for the first time, it takes quite a long time to initialize, and I would like this time so that the user knows that the program is still running. QSplashScreen exists but it doesn't run until QApplication is initialized, and since QApplication itself takes a long time to initialize - QSplashScreen loses its meaning. Ideally, a person should, after clicking on the application's shortcut, see the splash screen no later than a second. I tried Tk - it's very fast, but it takes up the main thread and is therefore not good ...
What do you recommend?

Answer 1

Try to write a standalone application showing splash, which will be killed by PID by the main application after it (the main application) is loaded.
