This applies to Python 3.8 under Debian-11 Bullseye.

Under curses getch should return the value of curses.KEY_B2
(350 decimal) when pressing the keypad 5.  Instead it
returns 574.

The simple program following the signature block
illustrates the problem.

# Put the following lines in a file
# Run from a terminal with:  python3

import curses as cs
def report(stdscr):
    print('press the keypad 5')
    global result
print('KEY_B2 (decimal): '+str(cs.KEY_B2))
print('input decimal value: '+str(result))

Your terminal emulator does not support this key. I tested it on Konsole and it returned 27. But on XTerm and on the Linux virtual console I get the expected result.
