Python以其简单易读的特性而声名鹊起，是一门备受欢迎的编程语言。其丰富的库和模块使其成为自动化各种任务的理想选择。在下面的集合中，提供了17个多功能的Python脚本，可帮助您简化工作流程，高效节省时间。

1. 自动化文件管理

1.1 对目录中的文件进行排序

import os
from shutil import move

def sort_files(directory_path):
    for filename in os.listdir(directory_path):
        if os.path.isfile(os.path.join(directory_path, filename)):
            file_extension = filename.split('.')[-1]
            destination_directory = os.path.join(directory_path, file_extension)

            if not os.path.exists(destination_directory):
                os.makedirs(destination_directory)

            move(os.path.join(directory_path, filename), os.path.join(destination_directory, filename))

1.2 删除空文件夹

import os

def remove_empty_folders(directory_path):
    for root, dirs, files in os.walk(directory_path, topdown=False):
        for folder in dirs:
            folder_path = os.path.join(root, folder)
            if not os.listdir(folder_path):
                os.rmdir(folder_path)

1.3 重命名多个文件

import os

def rename_files(directory_path, old_name, new_name):
    for filename in os.listdir(directory_path):
        if old_name in filename:
            new_filename = filename.replace(old_name, new_name)
            os.rename(os.path.join(directory_path, filename), os.path.join(directory_path, new_filename))

2. 使用Python进行网页抓取

    response = requests.get(url)
    soup = BeautifulSoup(response.text, 'html.parser')
    # Your code here to extract relevant data from the website

2.2 从网站下载图像

import requests

def download_images(url, save_directory):
    response = requests.get(url)

    if response.status_code == 200:
        images = response.json()  # Assuming the API returns a JSON array of image URLs

        for index, image_url in enumerate(images):
            image_response = requests.get(image_url)

            if image_response.status_code == 200:
                with open(f"{save_directory}/image_{index}.jpg", "wb") as f:
                    f.write(image_response.content)

2.3 自动提交表单

import requests

def submit_form(url, form_data):

    with open(file_path, 'r') as f:
        text = f.read()
        modified_text = text.replace(search_text, replace_text)

    with open(file_path, 'w') as f:
        f.write(modified_text)

    for recipient_email in recipients:
        message = MIMEMultipart()
        message['From'] = sender_email
        message['To'] = recipient_email
        message['Subject'] = subject
        message.attach(MIMEText(body, 'plain'))

    message['From'] = sender_email
    message['To'] = recipient_email
    message['Subject'] = subject
    message.attach(MIMEText(body, 'plain'))

    with open(file_path, "rb") as attachment:
        part = MIMEBase('application', 'octet-stream')
        part.set_payload(attachment.read())
        encoders.encode_base64(part)
        part.add_header('Content-Disposition', f"attachment; filename= {file_path}")

    server.starttls()
    server.login(sender_email, sender_password)

    now = datetime.now()
    reminder_date = datetime.strptime(reminder_date, '%Y-%m-%d')

    if now.date() == reminder_date.date():
        message = MIMEText(body, 'plain')
        message['From'] = sender_email
        message['To'] = recipient_email
