How to Auto-Generate "requirements.txt" With Current Python Project Dependencies?

In Python, you can generate a "requirements.txt" file automatically based on the installed packages in your current Python environment by using the following command:

pip freeze > requirements.txt

This command will create a "requirements.txt" file with the following packages from your current Python environment:

1. All installed packages with their versions pinned to an exact version number;
2. All transitive dependencies (i.e. all the packages that your top-level packages depend on).

This can be useful for ensuring that all developers and environments have the same set of dependencies installed. However, it's important to review and clean up this file to include only the necessary dependencies for your project and to regularly update it as your project evolves.

Once your "requirements.txt" file is generated, you can install the dependencies inside it using a package manager such as pip.
