I would even argue that the indices could be ignored entirely. We simply used the search space indices because wehave touse an index for pandas DataFrames, and this at least gives us a reference to which search space elements have been recommended (compared to the alternative were we would ...
Pandas version checks I have checked that this issue has not already been reported. I have confirmed this bug exists on the latest version of pandas. I have confirmed this bug exists on the main branch of pandas. Reproducible Example imp...
Indexing makes columns faster to query by creating pointers to where data is stored within a database. Imagine you want to find a piece of information that is within a large database. To get this information out of the database the computer will look through every row until it finds it....
