The Importance of Understanding Data Frame Order

In general at a high level. Data frames are ordered. And this can be any order so it doesn't necessarily mean that it's sorted but there is a difference between ordered and sorted in this case. This also means that operations that you do on a data frame have an output order associated with them. So, you can grab the fifth row or the 10th row or the first five rows or the last five. And interestingly it's always the same if that makes sense. The it also has column and row labels so row labels or row index is something that you know it emerged as this idea that you can have named rose and you can select rose by their name.
