10 Practical Python Scripts for Automation and Everyday Tasks

Looking for quick Python utilities? Below are ten concise scripts that solve common problems, each accompanied by a short description, the core code wrapped in tags, and practical tips.</p> <h2>1. Batch Rename Files (Office Tool)</h2> <p><strong>Scenario:</strong> Rename dozens of files automatically.</p> <code>import os path = "D:\\Files" # replace with your folder path for i, filename in enumerate(os.listdir(path)): os.rename(f"{path}/{filename}", f"{path}/文件_{i+1}.txt") Effect: Files become "文件_1.txt", "文件_2.txt", … Tips: Use double backslashes on Windows, single slashes on macOS/Linux. 2. One‑Click Download Web Images (Crawler Intro) Scenario: Save all images from a webpage. import requests from bs4 import BeautifulSoup url = "https://example.com" # replace with target page response = requests.get(url) soup = BeautifulSoup(response.text, "html.parser") for img in soup.find_all("img"): img_url = img.get("src") if img_url.startswith("http"): with open(img_url.split("/")[-1], "wb") as f: f.write(requests.get(img_url).content) Effect: All images are saved locally. Tips: Install dependencies with pip install requests beautifulsoup4 ; adjust for complex sites. 3. Automatic Email Sending (Work Efficiency) Scenario: Send daily reports automatically. import smtplib from email.mime.text import MIMEText msg = MIMEText("这是邮件正文", "plain", "utf-8") msg["Subject"] = "自动邮件标题" msg["From"] = "你的邮箱@qq.com" msg["To"] = "目标邮箱@163.com" with smtplib.SMTP_SSL("smtp.qq.com", 465) as server: server.login("你的邮箱@qq.com", "邮箱授权码") server.send_message(msg) Effect: Sends the email with one command. Tips: QQ mail requires an authorization code, not the login password. 4. Random Password Generator (Secure & Fun) Scenario: Create a strong password for new accounts. import random, string length = 12 chars = string.ascii_letters + string.digits + string.punctuation password = "".join(random.choice(chars) for _ in range(length)) print(f"你的新密码：{password}") Effect: Generates a 12‑character password containing letters, numbers, and symbols. Tips: Adjust length as needed for higher security. 5. Excel Automation (Data Lover's Favorite) Scenario: Process hundreds of rows without manual effort. import pandas as pd df = pd.read_excel("你的文件.xlsx") df["新列"] = df["旧列"] * 2 # example: double the values df.to_excel("新文件.xlsx", index=False) Effect: Reads, transforms, and saves the Excel file. Tips: Install with pip install pandas openpyxl and adjust column names. 6. Batch Image Compression (Save Space) Scenario: Reduce size of many photos. from PIL import Image import os path = "D:\\Pictures" # image folder for filename in os.listdir(path): if filename.endswith(".jpg"): img = Image.open(f"{path}/{filename}") img.resize((800, 600)).save(f"{path}/压缩_{filename}", quality=85) Effect: Images are resized to 800×600 with 85% quality. Tips: Install Pillow via pip install Pillow and customize dimensions. 7. Weather Query Script (Life Assistant) Scenario: Quickly check tomorrow's weather. import requests city = "Beijing" # replace with city name in English url = f"http://wttr.in/{city}?format=%C+%t" response = requests.get(url) print(f"{city}天气：{response.text}") Effect: Prints something like "Beijing天气：Sunny +15°C". Tips: Uses a free API, no registration required. 8. PDF Merger Tool (Document Organization) Scenario: Combine multiple PDFs into one. from PyPDF2 import PdfMerger merger = PdfMerger() for pdf in ["文件1.pdf", "文件2.pdf"]: # replace with actual filenames merger.append(pdf) merger.write("合并后的文件.pdf") merger.close() Effect: Produces a single merged PDF. Tips: Install with pip install PyPDF2 and ensure correct file names. 9. Text‑to‑Speech Conversion (Creative Play) Scenario: Turn text into an audio file. from gtts import gTTS text = "你好，我是Python小助手" tts = gTTS(text=text, lang="zh-CN") tts.save("output.mp3") Effect: Generates "output.mp3" containing the spoken text. Tips: Install with pip install gtts ; supports many languages. 10. Simple Snake Game (Relax) Scenario: Play a quick game after work. import pygame pygame.init() screen = pygame.display.set_mode((600, 400)) snake = [(200, 200)] direction = (20, 0) while True: for event in pygame.event.get(): if event.type == pygame.QUIT: pygame.quit() exit() snake.append((snake[-1][0] + direction[0], snake[-1][1] + direction[1])) snake.pop(0) screen.fill((0, 0, 0)) for pos in snake: pygame.draw.rect(screen, (0, 255, 0), (*pos, 20, 20)) pygame.display.flip() pygame.time.delay(100) Effect: A basic green snake moves on a black background. Tips: Install pygame via pip install pygame ; extend with food and keyboard controls. Which script fits your need? Try them out and feel free to leave comments for any questions.
