Create a ZIP file and use the zipfile module in Python. 1. Basic usage: Create a ZIP file through zipfile.ZipFile('example.zip', 'w'), and add individual files such as file1.txt and file2.txt using the write() method. 2. Advanced usage: Use os.walk() to traverse the directory, combine os.path.relpath() to maintain the relative path structure, and compress the entire folder into a ZIP file. 3. Compression options: 'w' mode will overwrite the original file, ZIP_DEFLATED enables compression, arcname avoids saving absolute paths. 4. Tips: It is recommended to skip .DS_Store, __pycache__ and other irrelevant files, and use os.path.exists() to check whether the file exists to ensure that the operation is safe and reliable. The whole process is simple and efficient, and the key is to correctly handle the path and compression mode.
Creating ZIP files is very simple in Python, mainly using the built-in zipfile module. Here is a practical and common example showing how to package one or more files into ZIP files.
? Basic example: Create a ZIP file
import zipfile
# Create a ZIP file and add the file with zipfile.ZipFile('example.zip', 'w') as zipf:
zipf.write('file1.txt') # Add a single file zipf.write('file2.txt')This creates a zip package called
example.zip, containingfile1.txtandfile2.txt.
? Advanced usage: Compress the entire folder
If you want to compress all files (including subdirectories) in a directory, you can do this:
import zipfile
import os
def zip_folder(folder_path, zip_name):
with zipfile.ZipFile(zip_name, 'w', zipfile.ZIP_DEFLATED) as zipf:
for root, dirs, files in os.walk(folder_path):
for file in files:
file_path = os.path.join(root, file)
# Use the relative path arcname = os.path.relpath(file_path, folder_path)
zipf.write(file_path, arcname)
# Use example zip_folder('my_folder/', 'my_folder.zip')This will compress all the contents under
my_folder/intomy_folder.zip, and the structure remains unchanged.
?? Add compression options description
-
'w': Write mode, it will overwrite existing ZIP files. -
zipfile.ZIP_DEFLATED: Enable compression. -
arcname: The file path name in ZIP to avoid saving absolute paths.
? Tips
- If you just temporarily package a few small files, just use
zipf.write(). - It is recommended to add judgment when traversing large folders, and skip unnecessary files such as
.DS_Store,__pycache__. - You can check whether the file exists in combination with
os.path.exists()to avoid errors.
Basically that's it. Not complicated, but it is easy to ignore the choice of path processing and compression mode.

css dark mode toggle example
Jul 30, 2025 am 05:28 AM
First, use JavaScript to obtain the user system preferences and locally stored theme settings, and initialize the page theme; 1. The HTML structure contains a button to trigger topic switching; 2. CSS uses: root to define bright theme variables, .dark-mode class defines dark theme variables, and applies these variables through var(); 3. JavaScript detects prefers-color-scheme and reads localStorage to determine the initial theme; 4. Switch the dark-mode class on the html element when clicking the button, and saves the current state to localStorage; 5. All color changes are accompanied by 0.3 seconds transition animation to enhance the user

The settings.json file is located in the user-level or workspace-level path and is used to customize VSCode settings. 1. User-level path: Windows is C:\Users\\AppData\Roaming\Code\User\settings.json, macOS is /Users//Library/ApplicationSupport/Code/User/settings.json, Linux is /home//.config/Code/User/settings.json; 2. Workspace-level path: .vscode/settings in the project root directory
css dropdown menu example
Jul 30, 2025 am 05:36 AM
Yes, a common CSS drop-down menu can be implemented through pure HTML and CSS without JavaScript. 1. Use nested ul and li to build a menu structure; 2. Use the:hover pseudo-class to control the display and hiding of pull-down content; 3. Set position:relative for parent li, and the submenu is positioned using position:absolute; 4. The submenu defaults to display:none, which becomes display:block when hovered; 5. Multi-level pull-down can be achieved through nesting, combined with transition, and add fade-in animations, and adapted to mobile terminals with media queries. The entire solution is simple and does not require JavaScript support, which is suitable for large
css full page layout example
Jul 30, 2025 am 05:39 AM
Full screen layout can be achieved using Flexbox or Grid. The core is to make the minimum height of the page the viewport height (min-height:100vh); 2. Use flex:1 or grid-template-rows:auto1frauto to make the content area occupy the remaining space; 3. Set box-sizing:border-box to ensure that the margin does not exceed the container; 4. Optimize the mobile experience with responsive media query; this solution is compatible with good structure and is suitable for login pages, dashboards and other scenarios, and finally realizes a full screen page layout with vertical centering and full viewport.
Full-Stack Web Development with Java, Spring Boot, and React

Selecting the Java SpringBoot React technology stack can build stable and efficient full-stack web applications, suitable for small and medium-sized to large enterprise-level systems. 2. The backend uses SpringBoot to quickly build RESTfulAPI. The core components include SpringWeb, SpringDataJPA, SpringSecurity, Lombok and Swagger. The front-end separation is achieved through @RestController returning JSON data. 3. The front-end uses React (in conjunction with Vite or CreateReactApp) to develop a responsive interface, uses Axios to call the back-end API, and ReactRouter
How to handle transactions in Java with JDBC?
Aug 02, 2025 pm 12:29 PM
To correctly handle JDBC transactions, you must first turn off the automatic commit mode, then perform multiple operations, and finally commit or rollback according to the results; 1. Call conn.setAutoCommit(false) to start the transaction; 2. Execute multiple SQL operations, such as INSERT and UPDATE; 3. Call conn.commit() if all operations are successful, and call conn.rollback() if an exception occurs to ensure data consistency; at the same time, try-with-resources should be used to manage resources, properly handle exceptions and close connections to avoid connection leakage; in addition, it is recommended to use connection pools and set save points to achieve partial rollback, and keep transactions as short as possible to improve performance.
Java Performance Optimization and Profiling Techniques
Jul 31, 2025 am 03:58 AM
Use performance analysis tools to locate bottlenecks, use VisualVM or JProfiler in the development and testing stage, and give priority to Async-Profiler in the production environment; 2. Reduce object creation, reuse objects, use StringBuilder to replace string splicing, and select appropriate GC strategies; 3. Optimize collection usage, select and preset initial capacity according to the scene; 4. Optimize concurrency, use concurrent collections, reduce lock granularity, and set thread pool reasonably; 5. Tune JVM parameters, set reasonable heap size and low-latency garbage collector and enable GC logs; 6. Avoid reflection at the code level, replace wrapper classes with basic types, delay initialization, and use final and static; 7. Continuous performance testing and monitoring, combined with JMH

fixture is a function used to provide preset environment or data for tests. 1. Use the @pytest.fixture decorator to define fixture; 2. Inject fixture in parameter form in the test function; 3. Execute setup before yield, and then teardown; 4. Control scope through scope parameters, such as function, module, etc.; 5. Place the shared fixture in conftest.py to achieve cross-file sharing, thereby improving the maintainability and reusability of tests.
