Python shell doesn’t working with addEventListener

[Xam-Mlr]

Hello, I start 1 week ago, electron js with node js for a program that I have made in python, so I wanna use it in backend. So I put a listener on a html's button and try to execute a python file with your project and it didn't work. So I tried without being into a listener and it worked.
Do you know how could I do ?
Congratulations for your job
Thanks
