Hello, I'm happy to announce that CPython project is participating in hacktoberfest. I have just added the hacktoberfest topic to CPython's GitHub Repo ( https://github.com/python/cpython). Caveat: if we end up receiving too many spammy, invalid, and low-quality PRs which just adds burden to maintainers, we will opt-out of this immediately. I will be watching incoming PRs for the next week to determine whether we should opt-out. If you're participating in hacktoberfest, your contribution to the repo will count. Instead of receiving a t-shirt, you can also choose to have a tree planted on your behalf, which I personally recommend. If you're a core dev, you can also participate and get rewarded by reviewing and merging pull requests. If you spot spammy PRs, please add either the "spam" or "invalid" label. Another way to participate is by donating to participating open source projects. You can donate to CPython development through GitHub Sponsors ( https://github.com/sponsors/python) Hacktoberfest <https://hacktoberfest.digitalocean.com/> is an annual event organized by Digital Ocean, now in the 8th year, where aspiring contributors are encouraged to contribute to open source projects. I'm a member of the Hacktoberfest Advisory council <https://hacktoberfest.digitalocean.com/advisory-council>. If you have concerns, feedback, and suggestions about this event, please do let me know and I'll be sure to pass it along. Thank you.
