To automatically generate empty commits with custom messages using the git commit --allow-empty parameter, you can use the GitPython library in your Python script.
First, make sure you have GitPython installed, which you can install using pip [1]:

pip install GitPython

Here's a Python script to create empty commits with custom messages:

import os
import git
from git import Repo

def create_empty_commit(repo_path, message):
    repo = Repo(repo_path)
    index = repo.index
    index.commit(message, allow_empty=True)

def main():
    repo_path = os.getcwd()  # Replace with the path to your Git repository
    commit_count = int(input("Enter the number of empty commits to create: "))

    for i in range(commit_count):
        message = input(f"Enter a custom message for commit {i + 1}: ")
        create_empty_commit(repo_path, message)
        print(f"Empty commit {i + 1} created with message: {message}")

if __name__ == "__main__":
    main()

In this script, you are asked to input the number of empty commits you want to create, as well as custom commit messages for each commit. The script uses GitPython to create empty commits with the specified messages in the Git repository.
Replace repo_path with the path to your Git repository where you want to create these empty commits. The script iterates through the number of commits you specify, allowing you to create multiple empty commits with different custom messages.
