'lo,

I am currently trying to code a simple routine for an experiment we are planning to run. The experiment starts by entering a subject number and creating a bunch of files. I got that part working. Next, we want the screen to go blank and display a message. Something like 'Please fill in questionnaire 1 and press [ENTER] when you are done.'

My question is, how do you recommend I present a blank screen with a message like that that waits for a certain key to be pressed?

I have quite some programming experience but haven't worked with Python before so any hints are greatly appreciated. Thanks a lot in advance for your time!

Some extra info that might be relevant: We are running this on Windows XP (Service Pack 2) computers. The whole point of this is that the participant does not have access to the desktop or anything on the computer basically. We want the experiment to start and display a bunch of instructions on the screen that the subject has to follow without them being able to abort etc. Hope this makes sense.

If you're in python 2, use raw_input().

If you're using python 3, use input().

You can prompt the user for information and store the result as a string.

in python 2.x

response = raw_input("What would you like to do next?")

in python 3.x

response = input("What would you like to do next?")
