Hi @narimiran
First of all, thank you for being awesome. I subscribed to the Double Pendulum bot and am always thrilled when a simulation is posted.
I have often looked at the code and the care you took to write it. I came back with the crazy idea to a create triple pendulum. I read the README and saw the dependencies mentioned there. I learned that it is a custom to list your dependencies in a requirements.txt. This helps in automatically downloading the necessary dependencies.
I have created this issue as a token of my gratitude. If you are interested in a 'requirements.txt` I could create a pull-request that sets one up. If you could not be bother less, that is fine too.
