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.
