Ok Dennis,
You were correct. The following also works in the Windows 10 command window.
import time
import msvcrt
while "more work to do":
print("Getting data...")
time.sleep(1)
print("Saving data to file...")
time.sleep(1)
key = msvcrt.getwch()
#print('key: %s'%key) # just to show the result
if key == chr(27):
print("Pre-termination...")
time.sleep(1)
raise SystemExit("exit")
Note, I am using the "Esc" key to exit, which is one answer to my last
posting on this topic.

the following:
I am running the code with Python 3.6 on a windows 10 platform. I have
tried many approaches (mainly those posted on stackoverflow) but I have
yet to find an approach that works for this structure.
Note:
1) The code is executed in the windows 10 command window
2) I am not using wxPython, IDLE, or pyGame in this application.
3) The time to get the data, process it and write it to a file can
take from 0.5 sec to 1.5 sec
4) The key hit need not be echoed to the command window
And none of your searching found
https://docs.python.org/3/library/msvcrt.html
which is part of the standard library (and documented in the library
manual). The module IS Windows specific, you'd have to rewrite the code to
run on Linux.
Now, if your requirement was to detect a keypress WHILE the data
fetch/processing was happening, the solution will be different.
