使用Python启动网站 URL 快捷方式

在本文中，我们将使用快捷方式启动喜爱的网站，为此，我们将使用 Python 的sqlite3和webbrowser模块使用快捷方式启动您喜爱的网站。

sqlite3和webbrowser都是Python标准库的一部分，所以我们不需要单独安装任何东西。

最好的部分是，因为我们使用数据库来存储网站及其快捷方式，即使我们关闭终端或关闭 PC，您最喜欢的网站仍将保存在数据库中。因此，您无需每次执行脚本时都将自己喜欢的网站添加到数据库中。

方法：

• 如果它不存在，我们创建一个新数据库并将其连接到我们的数据库。
• 我们创建了不同的函数来从数据库中获取数据、打开一个网站、向数据库添加一个新网站以及从数据库中删除一个网站
• 我们调用一个 while 循环，这样我们的程序就可以监听用户的命令，直到他们退出
• 我们要求用户响应以执行特定任务

下面是实现：

Python3

import webbrowser  
import sqlite3        
  
# connecting to sqlite and creating
# an actual database
conn = sqlite3.connect("favorites.db")
  
c = conn.cursor()
  
c.execute("""CREATE TABLE IF NOT EXISTS favorites
        (title TEXT, url TEXT)""")
  
# Created a table named favorites
# (if it didn't already existed).
# Then inserted the headers  title 
# (which takes text as input)
# and  url  (which takes text as input)
def get_data():
    """
    Used to extract data from our database
    """
      
    c.execute('''SELECT * FROM favorites''')
    results = c.fetchall()
    return results
  
  
def get_fav(titl):
    """
    Used to extract the favorite website
    """
      
    c.execute('''SELECT * FROM favorites WHERE title=?''',
              (titl, ))
    return c.fetchone()
  
def add_fav(titl, url):
    """
    Used to add a new favorite website
    """
      
    c.execute("""INSERT INTO favorites (title, url) VALUES (?, ?)""",
              (titl, url))
    conn.commit()
  
def remove_fav(titl):
    """
    Used to remove a favorite website from the database
    """
      
    c.execute('''DELETE FROM favorites WHERE title=?''',
              (titl, ))
    conn.commit()
  
# A loop to listen to commands from the user
while True:
    print()
  
    # printing each statement like 
    # this to keep the code clean
    print("Press v to visit a favorite,", end=" ")
    print("ls for list,", end=" ")
    print("add to add a new item,", end=" ")
    print("rm to delete,", end=" ")
    print("q to quit:", end=" ")
  
    # taking input command from the user
    response = input("")
  
    if response.lower() == "v":
        shortcut = input("Enter the shortcut for the website: ")
        record = get_fav(shortcut)
  
        try:
            # opening the selected website in the browser
            webbrowser.open(record[1])
  
        except TypeError:
            # if we don't have the shortcut 
            # in the database, print this:
            print('This shortcut does not exist in the database')
  
    elif response.lower() == "ls":
        # printing the items in the database
        print(get_data())
  
    elif response.lower() == "add":
        # adding a new website to the database
        destination = input(
            "Enter URL for the shortcut (Example -> https://xyz.com): ")
  
        # adding the shortcut to the above website in
        # the database
        shortcut = input("Enter the shortcut for the URL: ")
  
        add_fav(shortcut, destination)
  
    elif response.lower() == "rm":
        
        # removing an item from the database
        shortcut = input(
            "Enter the shortcut for the URL you want to remove: ")
        remove_fav(shortcut)
        print("Removed Successfully")
  
    elif response.lower() == "q":
        break
  
    else:
        print("Enter a valid command")
