python 的 zipfile 提供了非常便捷的方法来压缩和解压 zip 文件。

例如,在py脚本所在目录中,有如下文件:

复制代码 代码如下:
readability/readability.js
readability/readability.txt
readability/readability-print.css
readability/sprite-readability.png
readability/readability.css

将 readability 目录中的文件压缩到脚本所在目录的 readability.zip 文件中,保持相同的文件结构,然后打印出生成的压缩包 的文件列表,再用两种方式分别解压文件到脚本所在目录的 output 目录和 output/bak 目录中。

脚本如下:

#!/usr/vin/env python
# coding: utf-8
"""

import os
import zipfile

def compress(zip_file, input_dir):
  f_zip = zipfile.ZipFile(zip_file, 'w')
  for root, dirs, files in os.walk(input_dir):
    for f in files:
      # 获取文件相对路径,在压缩包内建立相同的目录结构
      abs_path = os.path.join(os.path.join(root, f))
      rel_path = os.path.relpath(abs_path, os.path.dirname(input_dir))
      f_zip.write(abs_path, rel_path, zipfile.ZIP_STORED)

def extract(zip_file, output_dir):
  f_zip = zipfile.ZipFile(zip_file, 'r')

  # 解压所有文件到指定目录
  f_zip.extractall(output_dir)

  # 逐个解压文件到指定目录
  for f in f_zip.namelist():
    f_zip.extract(f, os.path.join(output_dir, 'bak'))

def printdir(zip_file):
  f_zip = zipfile.ZipFile(zip_file, 'r')
  print '== printdir() ============================'
  f_zip.printdir()
  print
  print '== namelist() ============================'
  for f in f_zip.namelist():
    print f

if __name__ == '__main__':
  zip_file = 'readability.zip'
  compress(zip_file, os.path.join(os.getcwd(), 'readability'))
  printdirzip_file)
  extract(zip_file, 'output')
Copy after login

How to optimize database performance after mysql installation How to optimize database performance after mysql installation Apr 08, 2025 am 11:36 AM

MySQL performance optimization needs to start from three aspects: installation configuration, indexing and query optimization, monitoring and tuning. 1. After installation, you need to adjust the my.cnf file according to the server configuration, such as the innodb_buffer_pool_size parameter, and close query_cache_size; 2. Create a suitable index to avoid excessive indexes, and optimize query statements, such as using the EXPLAIN command to analyze the execution plan; 3. Use MySQL's own monitoring tool (SHOWPROCESSLIST, SHOWSTATUS) to monitor the database health, and regularly back up and organize the database.

The Enterprise Edition provides comprehensive commercial support for applications that require a stable, reliable, high-performance database and willing to pay for support. Factors considered when choosing a version include application criticality, budgeting, and technical skills. There is no perfect option, only the most suitable option, and you need to choose carefully according to the specific situation.

The loading interface of PS card may be caused by the software itself (file corruption or plug-in conflict), system environment (due driver or system files corruption), or hardware (hard disk corruption or memory stick failure). First check whether the computer resources are sufficient, close the background program and release memory and CPU resources. Fix PS installation or check for compatibility issues for plug-ins. Update or fallback to the PS version. Check the graphics card driver and update it, and run the system file check. If you troubleshoot the above problems, you can try hard disk detection and memory testing.
