10 Practical Python Scripts to Boost Your Productivity

Python is a versatile language for everyday tasks. This article presents ten ready‑to‑use scripts that can automate common workflows, ranging from file management to simple games.

1. Batch rename files (office tool)

Scenario: Rename dozens of files in a folder without manual effort.

<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")
</code>

Effect: Files are renamed to “文件_1.txt”, “文件_2.txt”, …

Tips: Use double backslashes on Windows, single slash on macOS/Linux.

2. One‑click download webpage images (web scraping starter)

Scenario: Batch‑save images from a website.

<code>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)
</code>

Effect: All images on the page are downloaded locally.

Tips: Install dependencies with pip install requests beautifulsoup4 ; complex sites may need code adjustments.

3. Automatic email sending (work efficiency)

Scenario: Send daily reports to your boss automatically.

<code>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)
</code>

Effect: Sends the email with one command.

Tips: QQ email authorization code is generated in “Settings → Account”, not the login password.

4. Random password generator (secure & fun)

Scenario: Quickly create a strong password for a new account.

<code>import random
import 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}")
</code>

Effect: Generates a 12‑character password containing letters, digits, and symbols.

Tips: Adjust length as needed; longer passwords increase security.

5. Excel automation (data‑handy)

Scenario: Process hundreds of rows in Excel without manual work.

<code>import pandas as pd
df = pd.read_excel("你的文件.xlsx")
df["新列"] = df["旧列"] * 2  # example: double a column
df.to_excel("新文件.xlsx", index=False)
</code>

Effect: Reads the Excel file, manipulates data, and saves a new file.

Tips: Install dependencies with pip install pandas openpyxl ; adjust column names to match your file.

6. Batch compress images (save space)

Scenario: Reduce the size of many photos.

<code>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)
</code>

Effect: Images are resized to 800×600 with 85% quality.

Tips: Install Pillow via pip install Pillow ; customize dimensions and quality as needed.

7. Weather query script (life assistant)

Scenario: Quickly check tomorrow’s weather.

<code>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}")
</code>

Effect: Prints output like “Beijing天气：Sunny +15°C”.

Tips: Free API, no registration required.

8. PDF merge tool (document organization)

Scenario: Combine multiple PDFs into a single file.

<code>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()
</code>

Effect: Produces one merged PDF.

Tips: Install with pip install PyPDF2 ; ensure file names are correct.

9. Text‑to‑speech conversion (creative use)

Scenario: Turn text into an audio file to share with friends.

<code>from gtts import gTTS
text = "你好，我是Python小助手"
tts = gTTS(text=text, lang="zh-CN")
tts.save("output.mp3")
</code>

Effect: Generates a Chinese voice file named output.mp3 .

Tips: Install with pip install gtts ; supports many languages.

10. Simple Snake game (relaxation)

Scenario: Play a quick game after a long work session.

<code>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)
</code>

Effect: A simple green snake moves on a black background.

Tips: Install pygame via pip install pygame ; full version can add food and keyboard control.

These ten scripts cover a wide range of practical scenarios—from office automation to entertainment—providing ready‑to‑run code, clear explanations, and useful tips to help you get started quickly.
