Join Jonathan Fernandes for an in-depth discussion in this video Index, part of pandas Essential Training.
- [Instructor] Indexing.…The index object is an immutable array,…and indexing allows you to access…a row or a column using a label.…This is what makes Pandas special,…because typically in other programming languages,…you cannot access an array using labels.…Let's head over to the Jupyter notebook…to look at a couple of examples.…So let's import Pandas's PD and let's import…our CSV dataset into our dataframe oo.…
To try and understand a little bit more about indexes,…let's look at their type, and you can see…that an index has its own type…and is not series or a dataframe.…Let's look at the hundredth element for this dataframe.…So oo, index, and 100,…and we can see that it's returned…the number 100 because that's the hundredth element…or the hundredth element in that dataframe.…Now indexes are immutable,…so that means we cannot change them.…
So oo.index, and if I try and change 100…to become, say, five, I get an error.…I get an "Index does not support mutable operations" error.…In this video, we covered the basic properties of the index,…
