I have got a dataframe like:
*nothing*            open          high
2020-01-12            122            59
2020-01-13            113            52
2020-02-14            144            64
2020-03-15            135            64
How can I only select rows from 2020-01-13 to 2020-02-14 using a filter? I'm aware there are more questions like these but this dataframe doesn't have a name for the date column (e.g. the date is the index).
Thank you!
