Converting Python's requirements.txt into Homebrew formula resources

For developers who maintain both Python and Homebrew packages, you've likely found that managing dependencies between the two ecosystems can be a bit challenging. Today, I am going to share a Python function that I wrote that automates the conversion of a Python requirements.txt file into Homebrew resource blocks. This can be a real time-saver, ensuring you have the correct dependencies for your Homebrew formula.

In Python, requirements.txt is the standard way to specify package dependencies with their corresponding versions. In a Homebrew formula, dependencies can be listed as 'resources'. Each resource block defines a package dependency, including its download URL and a SHA256 hash for verification.
