What is the difference between Git and Svn

When you open PyCharm for the first time, you should first create a new project and select a virtual environment, and then be familiar with the editor area, toolbar, navigation bar, and status bar. Set up Darcula themes and Consolas fonts, use smart tips and debugging tools to get more efficient, and learn Git integration.

Social security number verification is implemented in PHP through regular expressions and simple logic. 1) Use regular expressions to clean the input and remove non-numeric characters. 2) Check whether the string length is 18 bits. 3) Calculate and verify the check bit to ensure that it matches the last bit of the input.

The steps to effectively use graphical tools to compare the differences in Git versions include: 1. Open GitKraken and load the repository, 2. Select the version to compare, 3. View the differences, and 4. In-depth analysis. Graphical tools such as GitKraken provide intuitive interfaces and rich features to help developers understand the evolution of code more deeply.

The gitstatus command is used to display the status of the working directory and temporary storage area. 1. It will check the current branch, 2. Compare the working directory and the temporary storage area, 3. Compare the temporary storage area and the last commit, 4. Check untracked files to help developers understand the state of the warehouse and ensure that there are no omissions before committing.

To develop a complete Python Web application, follow these steps: 1. Choose the appropriate framework, such as Django or Flask. 2. Integrate databases and use ORMs such as SQLAlchemy. 3. Design the front-end and use Vue or React. 4. Perform the test, use pytest or unittest. 5. Deploy applications, use Docker and platforms such as Heroku or AWS. Through these steps, powerful and efficient web applications can be built.

Verifying an IMEISV string in PHP requires the following steps: 1. Verify the 16-bit numeric format using regular expressions. 2. Verify the validity of the IMEI part through the Luhn algorithm. 3. Check the validity of the software version number. The complete verification process includes format verification, Luhn checking and software version number checking to ensure the validity of IMEISV.

Create tags on remote repository using gitpushorigin, delete tags using gitpushorigin--delete. The specific steps include: 1. Create a local tag: gittagv1.0. 2. Push to remote: gitpushoriginv1.0. 3. Delete local tag: gittag-dv1.0. 4. Delete remote tag: gitpushorigin--deletev1.0.

VSCode solves the problems of multilingual project coding and garbled code including: 1. Ensure that the file is saved with correct encoding and use the "redetection encoding" function; 2. Set the file encoding to UTF-8 and automatically detect the encoding; 3. Control whether to add BOM; 4. Use the "EncodingConverter" plug-in to convert encoding; 5. Use the multiple workspace functions to set encoding for different sub-projects; 6. Optimize performance and ignore unnecessary file monitoring. Through these steps, the coding problem of multilingual projects can be effectively dealt with.
