Ignore part of file in git when using on 2 different computers python

Ignoring parts of a file in a Git repository when working on different computers is a common requirement. This can be accomplished using Git's built-in feature called .gitignore and using the .gitattributes file to specify how Git should handle certain files. In this tutorial, we'll walk you through the process of ignoring parts of a file when working with Python code on two different computers.
Prerequisites:
Step 1: Create a New Git Repository
If you haven't already, create a new Git repository on one of your computers:
Step 2: Create a .gitignore File
In the root of your Git repository, create a .gitignore file using a text editor (e.g., touch .gitignore or create it using your text editor).
Add the patterns for files or directories you want to ignore. For example, to ignore Python bytecode files, add the following lines to your .gitignore:
This will ensure that Python bytecode files and the __pycache__ directory are ignored.
Step 3: Create a .gitattributes File
Create a .gitattributes file in your Git repository using a text editor (e.g., touch .gitattributes or create it using your text editor).
In the .gitattributes file, you can specify which parts of a file you want to ignore. For example, let's say you have a configuration file named config.ini, and you want to ignore a specific section in that file.
In the example above, we've specified that the config.ini file should use a custom filter named ignore_section. We'll define this filter in the next step.
Step 4: Define a Custom Filter in Git
You need to define the custom filter in your Git configuration. To do this, open a terminal and run the following command:
In this example, we define a custom filter named ignore_section and specify that it should run the clean_config.py script when cleaning the file (on git add), and it should simply pass the content through cat when smudging the file (on git checkout).
Step 5: Create the Python Script
Create the clean_config.py Python script in the same directory as your .gitattributes and .gitignore files:
This script will clean the config.ini file by removing the specified section named "secret_section" when adding it to the Git repository. When checking out the file, Git will pass the content through without any changes.
Step 6: Use the Filtered Configuration File
Now you can use the filtered configuration file in your Python code. When working on different computers, Git will automatically apply the filter, so you won't have the ignored section in your wor
