Thank you for opening a Pull Request! Before submitting your PR, there are a few things you can do to make sure it goes smoothly: - [ ] Make sure to open an issue as a [bug/issue](https://togithub.com/googleapis/python-bigquery-dataframes/issues/new/choose) before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea - [ ] Ensure the tests and linter pass - [ ] Code coverage does not decrease (if any source code was changed) - [x] Appropriate docs were updated (if necessary) - [x] `Series.between()`: https://screenshot.googleplex.com/BhHpZsL7S9d3FsG - [x] `Series.cumprod()`: https://screenshot.googleplex.com/7o7gDNwJZEWst84 Fixes #<issue_number_goes_here> 🦕
