python3 NOT waiting for user input

Hello
I know I ask in arduino forum.
I also asked in raspberry pi forum and I'm waiting for answers.
I use python3 and I have 2 simple questions:

  1. Is there a way to have an input without the program waiting for the user to give it ?
  2. If first question doesn't work ,is there a way to check if a button has not been pressed?

I use getch.getch() as input ,but If I want to print (for example) "Hello" for ever ,it doesn't work ,because it waits for user input.

I really need your help!!!
I'm in desperation...
Thanks a lot !!!

Please read and follow the instructions in the "How to use this forum" post.

If you cannot get support for Python in the Python forums, perhaps use something else where you can get support ?

This is not a Python programming Forum.

In my experience Google knows the answer to most Python programming questions.
