It turns out that on Windows 10 it works for old console API if you do this:
-----
import sys
def clear_terminal():
if sys.platform == 'win32':
import ctypes
kernel32 = ctypes.windll.kernel32
# turn on the console ANSI colour handling
kernel32.SetConsoleMode(kernel32.GetStdHandle(-11), 7)
sys.stdout.write('\x1b[2J' '\x1b[H')
-----
The above should work in all but the old none ANSI terminals.
