How to add reaction to arrow keys in python?

Question

I'm trying to add a reaction to arrow key. While I was trying to, I deciced to try just print the reaction when the key is pressed, as I found here. When I write anything to console terminal, nothing happens. I am using PyCharm. Q: How to make it print the value as it should print?

 import msvcrt
 while True:
    if msvcrt.kbhit():
       key = msvcrt.getch()
       print(key)

this doesn't run because of indentation. What is the actual error you are getting? Are you on windows? Why is that linked answer the one you are trying? — Ryan Haining, Oct 05 '18 at 20:37

Edit : Under run configuration enable this - Emulate terminal in output console (see below)

Remove extra indentation

Error I get

File "run.py", line 2 while True: ^ IndentationError: unexpected indent

Code should be indented like this. Tested and it works.

import msvcrt
while True:
  if msvcrt.kbhit():
      key = msvcrt.getch()
      print(key)

The indetation isn't the problem, problem is, that the terminal do nothing if I press arrow key. I expected any output like the value of the key. – carolinesed Oct 05 '18 at 20:42
So the only way how to make it print the value is to use powerShell? Or is there any way how to make it in Pycharm? – carolinesed Oct 05 '18 at 20:44
Reading that this a problem with Pycharm. Still doing research. – Hassan Voyeau Oct 05 '18 at 20:49
Downloaded Pycharm and tested it. See updated answer for fix. – Hassan Voyeau Oct 05 '18 at 21:02

And you just run this script and press arrow keys in terminal? – carolinesed Oct 05 '18 at 21:06
Correct. My screenshot shows me pressing h key but it works for arrow keys and other keys. – Hassan Voyeau Oct 05 '18 at 21:07
