1、短网址生成器

编写一个Python脚本，使用API缩短给定的URL。

from __future__ import with_statement
import contextlib
try:
    from urllib.parse import urlencode
except ImportError:
    from urllib import urlencode
try:
    from urllib.request import urlopen
except ImportError:
    from urllib2 import urlopen
import sys

def make_tiny(url):
    request_url = ('http://tinyurl.com/api-create.php?' + 
    urlencode({'url':url}))
    with contextlib.closing(urlopen(request_url)) as response:
        return response.read().decode('utf-8')

def main():
    for tinyurl in map(make_tiny, sys.argv[1:]):
        print(tinyurl)

if __name__ == '__main__':
    main()

兄弟们学习python，有时候不知道怎么学，从哪里开始学。掌握了基本的一些语法或者做了两个案例后，不知道下一步怎么走，不知道如何去学习更加高深的知识。 那么对于这些大兄弟们，我准备了大量的免费视频教程，PDF电子书籍，以及视频源的源代码！ 还会有大佬解答！ 都在这个群里了 点这里立即进裙 欢迎加入，一起讨论 一起学习！

2、故事生成器

每次用户运行程序时，都会生成一个随机的故事。

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。

color = input("Enter a color:“)
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!")
    computer = random.choice(choices)

8、维基百科文章摘要

使用一种简单的方法从用户提供的文章链接中生成摘要。

你可以使用爬虫获取文章数据，通过提取生成摘要。

from bs4 import BeautifulSoup
import re
import requests
import heapq
from nltk.tokenize import sent_tokenize,word_tokenize
from nltk.corpus import stopwords

url = str(input("Paste the url"\n"))num = int(input("Enter the Number of Sentence you want in the summary"))
num = int(num)
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'}#url = str(input("Paste the url......."))
res = requests.get(url,headers=headers)summary = ""
soup = BeautifulSoup(res.text,'html.parser') content = soup.findAll("p")
for text in content:
    summary +=text.text 
def clean(text):    text = re.sub(r"\[[0-9]*\]"," ",text)
    text = text.lower()    text = re.sub(r'\s+'," ",text)    text = re.sub(r","," ",text)
    return text
summary = clean(summary)
print("Getting the data......\n")


##Tokenixing
sent_tokens = sent_tokenize(summary)
summary = re.sub(r"[^a-zA-z]"," ",summary)
word_tokens = word_tokenize(summary)
## Removing Stop words

word_frequency = {}stopwords =  set(stopwords.words("english"))

for word in word_tokens:
    if word not in stopwords:
        if word not in word_frequency.keys():
            word_frequency[word]=1
        else:
            word_frequency[word] +=1
maximum_frequency = max(word_frequency.values())
print(maximum_frequency)          
for word in word_frequency.keys():
    word_frequency[word] = (word_frequency[word]/maximum_frequency)
print(word_frequency)
sentences_score = {}
for sentence in sent_tokens:
    for word in word_tokenize(sentence):
        if word in word_frequency.keys():            if (len(sentence.split(" ")))
