can you merge master Is this identical to https://github.com/pandas-dev/pandas/pull/36878? Thanks @skorani - the task here is to apply `blacken-docs`, not to find and replace single quotes with double quotes, let us know if you need help @skorani - are you still interested in working on this? Otherwise we can close. Thanks > @skorani - are you still interested in working on this? Otherwise we can close. Thanks

The relevant issue here has been closed, so I think safe to close this as well. Thanks anyways @skorani for the PR, there are other good first issues if you wanted to take a look at those.
