1. 文件重命名工具

import os

def rename_files(directory, prefix):

for filename in os.listdir(directory):

file_path = os.path.join(directory, filename)

if os.path.isfile(file_path):

new_filename = f"{prefix}_{filename}"

new_file_path = os.path.join(directory, new_filename)

os.rename(file_path, new_file_path)

print(f"Renamed '{filename}' to '{new_filename}'")

directory = '/path/to/your/files'

prefix = 'file'

rename_files(directory, prefix)

2. 备份文件夹至ZIP文件

import zipfile

import os

def backup_to_zip(folder):

folder = os.path.abspath(folder) # Make sure the folder is absolute.

number = 1

while True:

zip_filename = f"backup_{number}.zip"

if not os.path.exists(zip_filename):

break

number += 1

print(f"Creating {zip_filename}...")

backup_zip = zipfile.ZipFile(zip_filename, 'w')

for foldername, subfolders, filenames in os.walk(folder):

print(f'Adding files in {foldername}...')

backup_zip.write(foldername)

for filename in filenames:

new_base = os.path.basename(folder) + '_'

if filename.startswith(new_base) and filename.endswith('.zip'):

continue # skip zip files starting with the new base name

backup_zip.write(os.path.join(foldername, filename))

backup_zip.close()

print("Backup Complete.")

backup_to_zip('/path/to/your/folder')

3. PDF页面合并工具

from PyPDF2 import PdfReader, PdfWriter

def merge_pdfs(paths, output):

pdf_writer = PdfWriter()

for path in paths:

pdf_reader = PdfReader(path)

for page in range(len(pdf_reader.pages)):

pdf_writer.add_page(pdf_reader.pages[page])

with open(output, 'wb') as fh:

pdf_writer.write(fh)

paths = ['/path/to/file1.pdf', '/path/to/file2.pdf']

output = '/path/to/output.pdf'

merge_pdfs(paths, output)

4. 文本替换工具

import re

def replace_text_in_file(filename, old_text, new_text):

with open(filename, 'r') as file:

file_data = file.read()

file_data = re.sub(old_text, new_text, file_data)

with open(filename, 'w') as file:

file.write(file_data)

filename = '/path/to/your/file.txt'

old_text = 'old_text'

new_text = 'new_text'

replace_text_in_file(filename, old_text, new_text)

5. 图片压缩工具

from PIL import Image

def compress_image(input_image_path, output_image_path, quality=85):

picture = Image.open(input_image_path)

picture.save(output_image_path, optimize=True, quality=quality)

input_image_path = '/path/to/your/image.jpg'

output_image_path = '/path/to/compressed/image.jpg'

compress_image(input_image_path, output_image_path)

6. 网页抓取工具

import requests

from bs4 import BeautifulSoup

def get_page_title(url):

response = requests.get(url)

soup = BeautifulSoup(response.text, 'html.parser')

title = soup.title.string

return title

url = 'https://example.com'

title = get_page_title(url)

print(f"The title of the webpage is: {title}")

7. Excel数据处理工具

import pandas as pd

def process_excel(file_path, sheet_name):

data = pd.read_excel(file_path, sheet_name=sheet_name)

# 进行数据处理...

processed_data = data[data['column_name'] > 10] # 示例：筛选大于10的数据

processed_data.to_excel('processed_data.xlsx', index=False)

file_path = '/path/to/your/excel.xlsx'

sheet_name = 'Sheet1'

process_excel(file_path, sheet_name)

8. 发送邮件工具

import smtplib

from email.mime.multipart import MIMEMultipart

from email.mime.text import MIMEText

def send_email(subject, body, to, server='localhost'):

msg = MIMEMultipart()

msg['From'] = 'sender@example.com'

msg['To'] = to

msg['Subject'] = subject

msg.attach(MIMEText(body, 'plain'))

with smtplib.SMTP(server) as smtp:

smtp.send_message(msg)

subject = 'Hello!'

body = 'This is a test email.'

to = 'receiver@example.com'

send_email(subject, body, to)

9. 日志分析工具

import re

def parse_logs(log_file_path):

pattern = r'\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}'

with open(log_file_path, 'r') as log_file:

for line in log_file:

match = re.search(pattern, line)

if match:

ip_address = match.group()

print(ip_address)

log_file_path = '/path/to/your/log.txt'

parse_logs(log_file_path)

10. 文件搜索工具 

import os

def search_files(directory, keyword):

for root, dirs, files in os.walk(directory):

for file in files:

if keyword in file:

print(os.path.join(root, file))

directory = '/path/to/search'

keyword = 'search_term'

search_files(directory, keyword)
