    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

    4、句子生成器

    通过用户提供的输入,来生成随机且唯一的句子。

    以用户输入的名词、代词、形容词等作为输入,然后将所有数据添加到句子中,并将其组合返回。

    pluralNoun= input("Enter a plural noun: ")
    celebrity input("Enter a celebrity: ")
    print("Roses are" ,color)
    print(pluralNoun+ " are blue")
    print(I love" , celebrity)
    -----------------------------------------------
    Red
    Teeth
    RDJ
    Roses are red. teeth are blue. I Love RDJ

    5、自动发送邮件

    编写一个Python脚本,可以使用这个脚本发送电子邮件。

    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

    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!")

    下载:haarcascade_frontalface_default.xml

    import cv2
    # Load the cascade
    face_cascade = cv2.CascadeClassifier('haarcascade_frontalface_default.xml')
    # Read the input image
    img = cv2.imread('images/img0.jpg')
    # Convert into grayscale
    gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
    # Detect faces
    faces = face_cascade.detectMultiScale(gray, 1.3, 4)
    # Draw rectangle around the faces
    for (x, y, w, h) in faces:
        cv2.rectangle(img, (x, y), (x+w, y+h), (255, 0, 0), 2)
        crop_face = img[y:y + h, x:x + w]  
        cv2.imwrite(str(w) + str(h) + '_faces.jpg', crop_face)
    # Display the output
    cv2.imshow('img', img)
    cv2.imshow("imgcropped",crop_face)
    cv2.waitKey()

    16、提醒应用

    创建一个提醒应用程序,在特定的时间提醒你做一些事情(桌面通知)。
    Time模块可以用来跟踪提醒时间,toastnotifier库可以用来显示桌面通知。

    from win10toast import ToastNotifier
    import time
    toaster = ToastNotifier()
    try:
        print("Title of reminder")
        header = input()
        print("Message of reminder")
        text = input()
        print("In how many minutes?")
        time_min = input()
        time_min=float(time_min)
    except:
        header = input("Title of reminder\n")
        text = input("Message of remindar\n")
        time_min=float(input("In how many minutes?\n"))
    time_min = time_min * 60
    print("Setting up reminder..")
    time.sleep(2)
    print("all set!")
    time.sleep(time_min)
    toaster.show_toast(f"{header}",
    f"{text}",
    duration=10,
    threaded=True)
    while toaster.notification_active(): time.sleep(0.005)    

    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

    import requests
    from bs4 import BeautifulSoup
    url = str(input("Paste article url\n"))
    
    def content(url):
      res = requests.get(url)
      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

            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)

    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)

    22、骰子模拟器

    创建一个程序来模拟掷骰子

    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
