Eryk,
Does this work for you:
import sys, os
def clear():
if sys.playform == 'win32':
os.system('cls')
else:
sys.stdout.write('\x1b[2J' '\x1b[H')
No need to address the list above because CLS does it.
No concern about CLS being a trojan becuse as a builtin to CMD and PowerShell
and it takes priority over cls.bat etc.
For all other platforms I'm assuming the VT100 level of ANSI escape sequences
is supported.
Barry
