如何在我的抛硬币Python代码中添加命令？

import random

def coin_flip():
    result = random.choice(['正面', '反面'])
    return result

while True:
    command = input("请输入命令（抛硬币/退出）：")
    
    if command == "抛硬币":
        result = coin_flip()
        print("硬币结果：", result)
    elif command == "退出":
        break
    else:
        print("无效的命令，请重新输入！")

import random

def coin_flip():
    result = random.choice(['正面', '反面'])
    return result

while True:
    command = input("请输入命令（抛硬币/退出）：")
    
    if command == "抛硬币":
        result = coin_flip()
        print("硬币结果：", result)
    elif command == "退出":
        break
    else:
        print("无效的命令，请重新输入！")
