一、石头剪刀布游戏
目标：创建一个命令行游戏，游戏者可以在石头、剪刀和布之间进行选择，与计算机PK。如果游戏者赢了，得分就会添加，直到结束游戏时，最终的分数会展示给游戏者。
提示：接收游戏者的选择，并且与计算机的选择进行比较。计算机的选择是从选择列表中随机选取的。如果游戏者获胜，则增加1分。

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':  
        print("Final Scores:")  
        print(f"CPU:{cpu_score}")  
        print(f"Plaer:{player_score}")  
        break  
    else:  
        print("That's not a valid play. Check your spelling!")  
    computer = random.choice(choices)

二、随机密码生成器
目标：创建一个程序，可指定密码长度，生成一串随机密码。
提示：创建一个数字+大写字母+小写字母+特殊字符的字符串。根据设定的密码长度随机生成一串密码。

import random  
passlen = int(input("enter the length of password" ))  
s=" abcdefghijklmnopqrstuvwxyz01234567890ABCDEFGHIJKL MNOPQRSTUVIXYZ!aN$x*6*( )?"  
p = ".join(random.sample(s,passlen ))  
print(p)  
----------------------------  
enter the length of password  
6  
Za1gB0

三、骰子模拟器
目的：创建一个程序来模拟掷骰子。
提示：当用户询问时，使用random模块生成一个1到6之间的数字。

import random;  
while int(input('Press 1 to roll the dice or 0 to exit:\n')): print( random. randint(1,6))  
--------------------------------------------------------------------  
Press 1 to roll the dice or 0 to exit  
1
4

四、自动发送邮件
目的：编写一个Python脚本，可以使用这个脚本发送电子邮件。
提示：email库可用于发送电子邮件。

import smtplib  
 
from email.message import EmailMessage 
 
email = EmailMessage() ## Creating a object for EmailMessage 
 
email['from'] = 'xyz name'   ## Person who is sending 
 
email['to'] = 'xyz id'       ## Whom we are sending 
 
email['subject'] = 'xyz subject'  ## Subject of email 
 
email.set_content("Xyz content of email") ## content of email 
 
with smtlib.SMTP(host='smtp.gmail.com',port=587)as smtp:      
 
## sending request to server  
 
    smtp.ehlo()          ## server object 
 
smtp.starttls()      ## used to send data between server and client 
 
smtp.login("email_id","Password") ## login id and password of gmail 
 
smtp.send_message(email)   ## Sending email 
 
print("email send")    ## Printing success message

五、闹钟
目的：编写一个创建闹钟的Python脚本。
提示：你可以使用date-time模块创建闹钟，以及playsound库播放声音。

from datetime import datetime     
from playsound import playsound  
alarm_time = input("Enter the time of alarm to be set:HH:MM:SS\n")  
alarm_hour=alarm_time[0:2]  
alarm_minute=alarm_time[3:5]  
alarm_seconds=alarm_time[6:8]  
alarm_period = alarm_time[9:11].upper()  
print("Setting up alarm..")  
while True:  
    now = datetime.now()  
    current_hour = now.strftime("%I")  
    current_minute = now.strftime("%M") 
    current_seconds = now.strftime("%S")  
    current_period = now.strftime("%p")  
    if(alarm_period==current_period):  
        if(alarm_hour==current_hour):  
            if(alarm_minute==current_minute):  
                if(alarm_seconds==current_seconds):  
                    print("Wake Up!")  
                    playsound('audio.mp3') ## download the alarm sound from link  
                    break
