正确格式化此代码以正确执行

Question

我正在尝试制作一个带有kali终端的游戏，我遇到了一些麻烦，在启动开始时，由于格式的原因，我无法调用-clear，这是什么我得到“ rootkali:~# -clear -未找到清除 rootkali:~# " 我不确定我应该如何处理这个问题，我该如何正确格式化？

import sys
import os

print('''
 -xss --v = start
 -xss --g -scp = scripts
 -clear = console will clear
    ''')

def cls():
    os.system('cls' if os.name == 'nt' else 'clear')

xss = str(input(" rootkali:~# "))

while xss != "-xss --v":
    print(f" {xss} is not found")
    xss = str(input(" rootkali:~# "))
else:
    print(" xss is starting....")
    print(" xss is running")
    xss = str(input(" rootkali~#: "))
    while xss != "-xss --g -scp":
        print(f" {xss} is not found")
        xss = str(input(" rootkali:~# "))
    else:
        print(" Severs starting.....")
        print(" Servers are running")
        xss = str(input(" rootkali~#: "))


while xss != "-clear":
    print(f" {xss} is not found")
    xss = str(input(" rootkali:~# "))
else:
    cls()
    os.execl(sys.executable, os.path.abspath(__file__), *sys.argv)


input()
